alsa problem - no sound

alsa problem - no sound

Post by Andreas Hiltenkam » Mon, 20 Nov 2000 17:56:28



Hi !
I've got a problem getting sound using a via sound chip
The alsa driver can be sucessfully loaded but I can't hear any sound.

Looking into /proc/asound/sndstat gives the following result
---------------------------------------------------------------------
--
Sound Driver:3.8.1a-980706 (ALSA v0.5.9b emulation code)
Kernel: Linux ibh03 2.2.14 #4 Sun Oct 22 08:59:05 CEST 2000 i686
Config options: 0

Installed drivers:
Type 10: ALSA emulation

Card config:
VIA 82C686A at 0xb800, irq 15

Audio devices: NOT ENABLED IN CONFIG

Synth devices: NOT ENABLED IN CONFIG

Midi devices:
0: MPU-401 (UART)

Timers:
7: system timer
What's wrong ? Why does sndstat tell me that here is no audio device,
synth device, system timer, mixer
How to enable them. I don't find anything about that in the alsa docu

lsmod looks as follows
Module                  Size  Used by
snd-card-via686a        7180   0
snd-pcm                28760   0  [snd-card-via686a]
snd-timer               8032   0  [snd-pcm]
snd-ac97-codec         23904   0  [snd-card-via686a]
snd-mixer              22608   0  [snd-ac97-codec]
snd-mpu401-uart         2312   0  [snd-card-via686a]
snd-rawmidi             9112   0  [snd-mpu401-uart]
snd-seq-device          3392   0  [snd-rawmidi]
snd                    34816   1  [snd-card-via686a snd-pcm snd-timer
snd-ac97-codec snd-mixer snd-mpu401-uart snd-rawmidi snd-seq-device]

Any suggestions whats wrong ?

Did you un-mute the channels?  By default, alsa mutes all output channels.
You can fix this with xmixer or amxier.

Try different IRQ's in isapnp.conf.  5 or 7 seem to work ok
as long as they're not taken up by something else.  Better yet,
check what 'doze uses if you have a dual boot system.

alsa problem - no sound

Post by James Stewar » Sun, 31 Dec 1899 09:00:00


Last I checked, the Alsa drivers intialize sound cards with all mixer
settings in the mute position.  So you have to manually unmute them (or put
a command in your startup files) .  You may already know this however.

1. azt2320 sound card and alsa sound drivers

Hi,
I'm following the alsa-sound-mini-HOWTO
to try to get my  azt2320 pnp sound card to make some (sound that is)
I've no problems with
./configure
make
make install
for the drivers, libs, and utils
but then I come to this:
(extract from the HOWTO)
4.6 Preparing the devices

There is a script in the driver-directory that will install the
ALSA-sound-devices in your /dev
directory. Type
       ./snddevices
from the driver-directory.
There should be a /dev/snd subdirectory now
<snip>
Problem: no /dev/snd directory is created.
Instead a symlink called snd is created pointing to
/proc/asound/dev
which does not exist.

please advise, if you can.
cheers
