Ubuntu 13.10 on Asus EEEPC1015PN - NO Sound, please help


Hi All,

Im an absolutely beginner with Linux/Ubuntu and have some issues with my netbook. I get no sound. If I have a look in the audio settings, there is no outut device listed and the volume is set to 0, wich cant be changed.

I tried it with alsamixer, there are 4 SPDIF active but they have a volume of 00, which also cant be modified.

I know thats not much info for you, but I have no idea. Would be great if someone could help me

thanks

Miro

If it's like mine with HDMI, you need to tell the kernel to turn on the audio.

Adding ‘radeon.audio=1′ to the line in /etc/defaults/grub with the other kernel options (grubcmdlinelinux_default) and then running update-grub and rebooting got my sound settings option available for HDMI. Then I could choose that option for sound output and finally got sound again via the digital video link.

Didnt work

Hey,

i tried to modify it. I aded the two lines, is it correct?

I get the following error while updating grub:
/usr/sbin/grub-mkconfig: 26: /etc/default/grub: radeon.audio=1′
(grubcmdlinelinux_default)

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo: File name too long


Otherwise I have some issues with the system, softwareupdater doesnt work, hangs up very often and so on.

thank you very much

try

sudo alsacntl init

and see if it helps. I've had to reinitialize some cards lately, for no apparent reason.

added 2 lines? - should only modify one, not add any. In

/etc/defaults/grub

look for the line that starts with

GRUB_CMDLINE_LINUX_DEFAULT=

it will have parameters like quiet and splash in double quotes. What you want to do is to add another parameter to that list:

radeon.audio=1

for more on this, see http://community.linuxmint.com/tutorial/view/1051 or do a search on radeon.audio=1

I don't know if Pulseaudio has gotten any less buggy with Ubuntu 13.10, but I've had sound issues before in Debian, and removing Pulseaudio fixed them. You might try that. Also, can you type lsmod in a terminal and post the output?

Do note that the HDMI radeon issue I was describing had nothing to do with ALSA or Pulseaudio or other sound systems. Until the kernel sets up an audio device, these audio systems won't even see it.

If you do see an HDMI device in your sound settings, then the kernel has identified the device, loaded the proper module, and enabled the interface to that device. Then you can use mixers and whatnot to control it. The common issue in this case is simply selecting the proper interface and making it the default.

What I was suggesting was when there is no HDMI sound device to control as happened with my EEE PC and on my AMD based mobo. It puzzled me why I couldn't even find an HDMI audio to turn on until I found out about this change in the kernel default for that particular module.

Ubuntu 13.10 on Asus EEEPC1015PN - NO Sound, please help

Hi guys

may thanks for your help. I think it is a hardware issue, cause I tried it as well with my windows harddisk I had inside before, same problem. soundcard not detected.

Anyway I got lot of error message after booting up, systemupdate is not working anymore and so on..is there any possibility to repair it or to have a look into an event log?

There is a specific fix for this netbook. Put the following in '/lib/modprobe.d/sound.conf':
Code:
options snd-hda-intel probe_mask=0xffff,0xfff2
Older distros have '/etc/modprobe.d' instead of '/lib/modprobe.d', and you should use whichever exists.
