New Install - ALSA Sound Problem
 
I just installed Slackware 8.1 on my Thinkpad i1400. The install went great except for a little fighting with lilo. I then went to install the alsa drivers for my sound card (opl3sa2) and followed the directions here.

Now, when I try to play an mp3 with amp or start up KDE the system completely locks up. I'm assuming KDE is trying to play a sound on startup.

I looked in /var/log/syslog but didn't see anything that stood out (I'll insert it at the end of this message.)

I was able to get this to work with Debian woody by following the same instructions that I linked to above. Any ideas on how to fix this?

Thanks,
Andrew

What version of the ALSA drivers are you using? And after you boot / init the soundcard does:

cat /proc/asound/cards

list an installed device?

I was trying this with the latest version, 0.9.0rc6. However I tried something else when I realized that the drivers for this card are actually included with Slackware.

I reinstalled Slackware and ran /sbin/modprobe opl3sa2. When I ran amp from the command line everything worked fine although at a really low volume. However, I can't get into KDE. If I reboot so the sound drivers aren't loaded KDE works find except it gives the error:

Error while initializing the sound driver

device /dev/dsp can't be opened (No such device)

The sound server will continue, using the null output device.

I tried fvwm2 with the sound drivers loaded and that works fine.

Just tried Gnome and I can login but playing an mp3 locks things up again.

ab42 01-17-2003 04:23 PM
So your sound card works fine in shell mode (ie no gui mode) but not in gui mode right?

Just running modprobe isn't sufficient to get your card working across the board. To my knowledge some of the apps in the various guis want to interface with a sound device using an OSS standard.

During the ALSA install, you should have seen portions relating to that. Not doing those instructions could be the source of your problems.

Running this command:

cat /proc/asound/cards

Should show your card if it is properly installed from an ALSA standpoint.

Ruunning this command:

alsamixer

is the best way to set the mixer levels using the ALSA drivers, as some of the other mixers don't read all the mixing channels in...

-- Another thing to try.... reinstall use the 'stable' drivers. The install instructions are slightly different, but they worked for me. I have sound in just the bash shell and any of the various gui desktops and window managers... albiet with a Yamaha chip but I think the ALSA drivers are well written across all chips.
