Slackware 10 Sound Problem
 
I installed Slackware 10 recently and have been unable to initialize any of the sound services. I installed the 2.6.7 kernel and still there is no sound (of any type). There are a variety of comments I can make:

1. I get an error message stating that there is no /dev/dsp (a listing shows that indeed none exist)

2. alsaconf does not provide any available drivers

3. alsamixer does not launch

4. I'm using a Dell Latitude D600 and all else is fully functional.

5. I attempted to remove the 4 alsa packages and reinstall them but nothing changed.

This the output of lspci -v:

00:1f.5 Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 Audio Controller (rev 01)
Subsystem: Dell Computer Corporation: Unknown device 011d
Flags: bus master, medium devsel, latency 0, IRQ 7
I/O ports at b800 [size=256]
I/O ports at bc40 [size=64]
Memory at f4fff800 (32-bit, non-prefetchable) [size=512]
Memory at f4fff400 (32-bit, non-prefetchable) [size=256]
Capabilities: [50] Power Management version 2

According to the Dell documentation, I'm using a SigmaTel sound device.

Can someone point me to a clear solution? Thanks in advance!

modprobe snd-ac97-codec or
modprobe ac97_codec

try downloading:
alsa-driver-1.0.5a.tar.bz2
alsa-lib-1.0.5.tar.bz2
alsa-utils-1.0.5.tar.bz2
from http://www.alsa-project.org/

Jeffmrg 08-08-2004 01:42 PM

Thanks for the reply, kodon. Before I start to install these, can you tell me how these files differ from the official slackware packages of almost the same name (but different suffix)? I already did install these:

alsa-driver-1.0.5a.i486-2.tgz
alsa-lib-1.0.5.i486-1.tgz
alsa-utils-1.0.5.i486-1.tgz

Will I get a more favorable outcome by compiling your recommended files vs. the above packages?

kodon 08-08-2004 01:46 PM

oh...sorry
just wanted to make sure you were up to date
as long as you already have 1.0.5 disregard my previous post

hmm...you're current and alsaconf doesn't recognize your card?

Tuttle 08-08-2004 02:25 PM

did you install the generic kernel from the /mnt/cdrom/testing/packages/linux-2.6.7 directory on cd2? If so, did you install the alsadriver package form that same directory?

suslik 08-08-2004 03:00 PM

Please, post your lsmod and lspci (full, no -v)
With lsmod I would like to see what and if any/wrong modules are loaded for sound.
With lspci I would know what chipset you are using = clue to what driver you need. (I am guessing i8x0)

Jeffmrg 08-08-2004 03:25 PM

I followed Tuttle's advice and installed the alsa from the CD (thanks). Alsaconf now runs and detects my sound system. Strangely enough, I still to not have sound, even with alsamixer up to near max for all. I did notice that in alsamixer my heaphone(??) histogram said <off> but I was able to take the level up graphically. I only mention this as my speaker plug is using the headphone jack from the PC. Also, I can no longer get at alsamixer and get a 'No mixer elems found'.

:) I havn't a sound on Slack 10 with via8233a too...
 
Hi.
Everything is OK, all modules loaded, no errors in compilation of alsa-drivers,-libs,-utils,-oss.When I use OSS modules - I have the sound, but from ALSA-silence.Kernels 2.6.7 and 2.4.x make same problems.Nothing under KDE, GNOME, XFCE,console too.
When I close KDE I have strange error:"ALSA lib pcm_hw:549(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed: Broken pipe" .
I prepared missing devices into make_extra_nodes.sh for udev, but no results.

My motherboard is SOLTEK SL-75DRV5, with VIA8233a.

Have you tried running "alsaconf"?

Jeffmrg: did you unmute all the controls too? silly question i know!

Jeffmrg 08-08-2004 09:35 PM

Thanks for the help, Tuttle. I now have sound. I did a few things to make this happen:

added snd-intel8x0m to my /etc/hotplug/blacklist file

obtained and istalled alsa (2.6.7) from Slackware 10 D2

unmuted (keystroke . [period] does this)

modified permissions on /dev/cdrom for use by all

Success.

This took some time and help from many.

Tuttle...Thx for the suggestion, but it was a first work after installation of ALSA ;)

Tuttle 08-09-2004 07:07 AM

Jeffmrg: It can be fiddly setting things up but you got there in the end.
re. cdrom permissions, here is my /etc/group file:

Code:

root::0:root
bin::1:root,bin,daemon
daemon::2:root,bin,daemon
sys::3:root,bin,adm
adm::4:root,adm,daemon
tty::5:
disk::6:root,adm,tuttle
lp::7:lp
mem::8:
kmem::9:
wheel::10:root
floppy::11:root
mail::12:mail
news::13:news
uucp::14:uucp
man::15:
audio::17:tuttle
video::18:tuttle
cdrom::19:tuttle
games::20:tuttle
slocate::21:
utmp::22:
smmsp::25:smmsp
mysql::27:
rpc::32:
sshd::33:sshd
gdm::42:
shadow::43:
ftp::50:
pop::90:pop
nobody::98:nobody
nogroup::99:
users::100:
console::101:

Notice how I have my name next to audio, video, disk etc... Try it in yours (changes take effect as soon as you change the file) this allows you to keep the system secure by not allowing everyone to access stuff.

marekjs: do you mean it's ok or is the problem still there?
