Bug 93506 – Alsa does not work but oss works with alsa emulating it.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Greg Furstenwerth 2005-05-21 23:11:42 UTC]

When trying to run alsa physically it does not work. If you are using it with
OSS emulation then it works. So you are able to run oss sound but not alsa.
Anything that trys to run alsa tends to segfault from what I have seen either
that or it just fails all together. This prevents me apparently from running any
native linux games properly with sound. I get sound with Cedega, XMMS and
Mplayer when running in OSS it works fine Alsa causes them to crash or not work.

Reproducible: Always
Steps to Reproduce:
1. Compile Alsa either in Kernel or alsa-driver
2. Turn up sound
3. Attempt to run anything with Alsa (aplay, native game, etc)

Actual Results:  
Segfaults on Native Games when using openalrc setting it to alsa. Trying to run
aplay causes a very nasty looping sound. Other things just outright dont work.

Expected Results:  
Played Sound.

There was a problem with a specific version which caused segmentation faults.
Upgrade to the latest version and report back. Another note:

Make sure that you dont use the in kernel driver because it's easy to mix
versions of the lib, the headers and the driver module in that case. Simply
follow the Gentoo Alsa Guide, and use alsa-driver from the tree.
