Repeated sound on Acer Aspire E1-521 Laptop

I'm trying to get the sound to work properly on my Acer Aspire E1-521-0851 Laptop, but it just doesn't want to play nice.

When I go to System -> Administration -> Soundcard Detection. Two devices are detected.

1. AMD Hudson Azalia Controller using module snd-hda-intel
2. AMD nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] using module snd-hda-intel

When I sound test the first (Hudson Azalia Controller), sound does play but it is very choppy and echoed. It's also very low and I have to adjust the slider to the right to hear anything. The sound test on the second does not produce anything.

Is there a bug, conflict, or some misconfiguration going on?

Here is my system information:

# cat /etc/redhat-release
CentOS release 5.9 (Final) Note: I started with CentOS 5.7 and did a #yum update

# uname -rmi
2.6.18-348.16.1.el5PAE i686 i386

I did see something at kernel.org
https://www.kernel.org/doc/Documenta...a/HD-Audio.txt

That mentioned if I got this in my dmesg:

hda-intel: Invalid position buffer, using LPIB read method instead.

That.... `position_fix=2` means to use the position-buffer. 0 is the default
value, the automatic check and fallback to LPIB as described in the
above. If you get a problem of repeated sounds, this option might
help.

How can I set this option without recompiling my kernel. I would like to send a kernel parameter at boot or do some configuration in modprobe.conf or asound.conf.


Follow is some more information that may be helpful. I also attached the output from the also-info.sh script.

I did adjust this file manually (/etc/asound.conf), because when I ran alsamixer is would display the ATI Wrestler HDMI Audio [Radeon HD 6250/6310] card, but without any controls. After that alsamixer would display controls with Card: HD-Audio Generic Chip: Realtek ALC269VB.

[root@localhost etc]# cat asound.conf

#HWCONF

pcm.!default { type hw card 1 device 0 }
ctl.!default { type hw card 1 }

I hope this is enough information to give me some hints on how to fix this problem. Thanks for any information you can provide and if you need more info., I'll get it right away.

Hi

The sound test on the second does not produce anything.

If this is a hdmi output device, how did you test?

pls study this part of your attachment

!!ALSA configuration files !!------------------------ !!System wide config file (/etc/asound.conf) #Generated by system-config-soundcard, do not edit by hand #HWCONF #DEV 0 pcm.!default { type hw card 1 device 0 } ctl.!default { type hw card 1 }

It suggests your second device is the default

Do you need to swap between devices for any reason?
If so, leaping ahead, because its the same kernel module for both devices
---you may be better off installing pulseaudio

In the meantime, you may prefer to delete that system wide config and replace with a
home user created file called .asoundrc contents to be (initially) as per
http://alsa.opensrc.org/Asoundrc

pcm.card0 { type hw card 0 } ctl.card0 { type hw card 0 }

then when you do a speaker test you know you are testing card 0
then adjust full reboot and test with a modified asoundrc for card 1----ok?

last being lazy I have not done the research but trust you so if

position_fix=2

is for card 0 you modify your modprobe.conf so it has this line

options snd-hda-intel position_fix=2

but please do one thing at a time to help trouble shooting....and full reboots
it may take longer but in the long run you will be able to give better feedback
if my advice is not helpful

and run

alsamixer

to adjust sound levels please

you can also have different sound levels set for each device,
but as you a newbie, you may be better off with pulseaudio
we will await your results first eh?

Hello Aug9

Thank you very much for the reply. It looks like you’re from Australia. I love that place. I spent two years up in the Gold Coast area. Unfortunately I had to leave.

Re: testing on the HDMI device – I thought the sound card utility would send it to the regular speakers, because the utility asked me if I heard a sound. But since you mention HDMI it would make more sense that it would need an HDMI device. (FYI – most of my experience is with kiosk and headless machines that don’t use sound.

I did set my second device as default, because that was the only way I could get a controllable ALSA mixer interface and any test sounds when I would issue # aplay /usr/share/sounds/alsa/Front_Center.wav.

I don’t need to swap between devices. I just need basic sound from my laptop speakers.

Unfortunately I need to stick with CentOS 5.7-5.9 and it doesn’t look like the main distro repositories have Pulse.

Ok, I created a /root/.asoundrc under card 0 and rebooted. Then ran # aplay /usr/share/sounds/alsa/Front_Center.wav, and got this error:
ALSA lib pcm_dmix.c:1008snd_pcm_dmix_open) unable to open slave
aplay: main:583: audio open error: No such file or directory

So now I changed /root/.asoundrc to card 1 and rebooted.

pcm.card1 { type hw card 1 } ctl.card1 { type hw card 1 }

And I still get the same error:

ALSA lib pcm_dmix.c:1008snd_pcm_dmix_open) unable to open slave aplay: main:583: audio open error: No such file or directory

The https://wiki.archlinux.org/index.php...d_Architecture site said if the above config doesn’t work try, which is very similar to my old /etc/asound.conf.

defaults.pcm.card 0 defaults.pcm.device 3 defaults.ctl.card 0

So, I move my old asound.conf to /root/.asoundrc and now I get sound, but repeats while playing the test. Front Front Front Front Front Front Front Front Front Center Center Center Center Center Center Center Center Center Center.

[root@localhost home]# cat /root/.asoundrc #Generated by system-config-soundcard, do not edit by hand #SWCONF #DEV 0 defaults.pcm.card 1 defaults.pcm.device 0 defaults.ctl.card 1

So now I will try: options snd-hda-intel index=0 position_fix=2

Doing a little research, it looks like adding position_fix=2 is for HDMI, which is really not what I need. As mentioned before regular speaker output is fine.

All my alsamixer settings are unmuted and set to 100.

One thing I did you was to enable the RPM Forge repository and download mplayer. And using mplayer, my .wav files play much better, but there is a little repeating at the end (but not nearly as bad as aplay) and .mp3 files play fine. Is it using its own sound configuration and not relying 100% on alsa. I think I need to dig deeper into the alsa configuration.

If my problems would be solved with pulseaudio, that would be great, but I don’t think I can install it on my CentOS 5.7 system.

I did test the same file in verbose mode using mplayer and aplay. Here is the output, maybe you see something that is causing the repeat issue. Once again, I really appreciate you trying to help me.

hi

firstly, its home/yourname/.asoundrc

don't run sound as root please.

delete the system wide /etc/asound* for the moment, we want nothing polluting your home folder setup
create home user .asoundrc as above as

pcm.card0 { type hw card 0 } ctl.card0 { type hw card 0 }

this should default you to card0.

I will come back later have to go out now

Hello

Thanks again for your help.

I was running as root just in case any permissions where getting in the way. Usually when I have a problem, I’ll run as root and once it’s working as root, I know can also get it working as a non-root user. That being said, I am following your instructions to a tee.

I’ve removed all /etc/asound* and created /home/antonio/.asoundrc, but the configuration

pcm.card0 { type hw card 0 } ctl.card0 { type hw card 0 }

does not work for me, nor does

pcm.card1 { type hw card 1 } ctl.card1 { type hw card 1 }

I get this error for both configurations:

ALSA lib pcm_dmix.c:1008snd_pcm_dmix_open) unable to open slave aplay: main:583: audio open error: No such file or directory

so I’ve reverted to my old configuration from /etc/asound.conf and copied it to ~/.asound

defaults.pcm.card 1 defaults.pcm.device 0 defaults.ctl.card 1

Which is my non-HDMI card.

It’s mentioned in this link (https://wiki.archlinux.org/index.php...rchitecture)if this does not work try

pcm.!default { type hw card 0 device 3 }

defaults.pcm.card 0 defaults.pcm.device 3 defaults.ctl.card 0

So I adapted for my card and device and was able to get sound from my laptop speakers, but once again it is repeating Front Front Front Front Front Front Front Front Front Center Center Center Center Center Center Center Center Center Center.

The output from the aplay command was…

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

I’ve been through the https://wiki.archlinux.org/index.php...d_Architecture page top to bottom and tried almost everything.


This link was interesting https://www.kernel.org/doc/Documenta...a/HD-Audio.txt and mentioned

`position_fix=1` means to use LPIB method explicitly.
`position_fix=2` means to use the position-buffer.
`position_fix=3` means to use a combination of both methods, needed
for some VIA controllers. The capture stream position is corrected
by comparing both LPIB and position-buffer values.
`position_fix=4` is another combination available for all controllers,
and uses LPIB for the playback and the position-buffer for the capture
streams.
0 is the default value for all other
controllers, the automatic check and fallback to LPIB as described in
the above. If you get a problem of repeated sounds, this option might
help.

I’ve tried all 4 position_fixs in /etc/modprobe.conf (options snd-hda-intel index=0 position_fix=#) and rebooted between each and still get the repeat sound.

Once again mplayer plays so much better than aplay. When it's mplayer with mp3s, it's perfect.

Any more insight is appreciated.

hi

soory I should have mentioned ---that sound-- is what you are supposed to hear, but you chose the Front_Center.wav

ok for now, delete all asoundrc asound* from /etc /home/yourname plse.

full reboot and post the contents of this command pls

cat /proc/asound/card0/codec#0 | grep Codec

2) aplay is very basic I use vlc myself but glad you are happy with mplayer and let keep it simple so more than happy we are looking at

I just need basic sound from my laptop speakers.

how many audio holes (= stacks) do you have eg one green one orange one blue? or just the 2?

Just to be blunt
when you use aplay without a timeout....you will hear repeated sounds.....thats normal

You may have nothing wrong.

Hello,

Per your request..

[root@localhost ~]# cat /proc/asound/card0/codec#0 | grep Codec Codec: ATI R6xx HDMI

Re: audio holes – on this laptop they are not color coded, but there are two – mic and headset.

Thanks again.

Antonio

Hello Aus9,

Just some more information, maybe it's helpful. I downloaded and install vlc and tried to test an MP3 and got alsa audio output error: cannot write: broken pipe.

Also tried to test the same .wav file I was using with aplay and got the same results. Repeat sound. front front front front front front front front front front center center center center center center center center center center

ok post the contents of these commands pls, if the same just show one

cat /proc/asound/devices
or
cat /proc/asound/pcm

we are going use your output to create a home .asoundrc file with the contents and forumula as follows

pcm.!default { type hw card <number> device <number> }

now from your earlier post we have

[root@localhost etc]# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Generic_1 [HD-Audio Generic], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0

so your last reply on this matter is you don't want hdmi but laptop speaker so the config can be half completed with

##############
pcm.!default {
type hw
card 0
device 0
}

part two......go into alsamixer and if no laptop speaker sound....with volumes raised etc
-----then and only then....mute the SPDIF control or its already muted unmute it

Hello Aus,

[antonio@localhost ~]$ cat /proc/asound/devices 2: : timer 3: [ 0- 3]: digital audio playback 4: [ 0- 0]: hardware dependent 5: [ 0] : control 6: [ 1- 0]: digital audio playback 7: [ 1- 0]: digital audio capture 8: [ 1- 0]: hardware dependent 9: [ 1] : control

[antonio@localhost ~]$ cat /proc/asound/pcm 00-03: HDMI 0 : HDMI 0 : playback 1 01-00: ALC269VB Analog : ALC269VB Analog : playback 1 : capture 1

The output from my initial aplay –l in my post is a little different now because back then I was adjusting the module loading order for each card in /etc/modprobe.com and trying to make the non-HDMI card be card 0 as I thought that could help. It did not.

If I leave modprobe.conf untouched, my current aplay –l is as follows. Please note, there are no asound* files under etc. and to be on the safe side I’ve done a reboot on each file modification.

[root@localhost ~]# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic_1 [HD-Audio Generic], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0

So following the content and formula you suggested, my current /home/antonio/.asoundrc is

pcm.!default { type hw card 1 device 0 }

Note when I had the following added to /home/antonio/.asoundrc file, I would experience the repeat issue on mplayer and vlc. When it’s removed, sound plays fine. Aplay is still giving me problems, so something is still awry. But for the moment I can live with using mplayer and vlc.

ctl.!default { type hw card 1 device 0 }

Once again, thanks for all of your help. If you see something obvious to get aplay working properly. I all ears.

Regards,

no I can't spot off hand but if you ever choose to play sound thru a hdmi cable you would use this output

[antonio@localhost ~]$ cat /proc/asound/pcm 00-03: HDMI 0 : HDMI 0 : playback 1 01-00: ALC269VB Analog : ALC269VB Analog : playback 1 : capture 1

and note that hdmi is 0 3 so your asoundrc would become ---with fingers and toes crossed

pcm.!default { type hw card 0 device 3 }

bye for now
