UT2004 sound problem

[Karel J. Bosschaart]

Hi,

Got my UT2004 DVD yesterday :-), but I have a problem with the sound:
it plays too slow, which makes the game unplayable. This is on -stable
(as of today). Relevant messages (other lines omitted) from UT2004:

fcntl: No such device or address
ioctl SETFRAGMENT: Invalid argument
<snip>
native_blitbuffer: select error occured
<snip>

the last message occurs when exiting UT2004. The process ut2004-bin
is stuck in 'pcmsyn' state and I have to kill it. 

In -current (same machine) sound is OK, and I only get the 'fcntl' message.

The sound in both UT2003 and UT2004 demo is working well on -stable. 
Things I tried:

- using my second sound card: same problem.
- copying openal.so from UT2003 and UT2004 demo to UT2004: no error
  messages anymore, but also no sound.
- this obscure sequence makes the sound work properly:
  1. reboot machine
  2. start UT2004 demo, and quit after watching the intro
  3. start UT2004. Now the sound is OK... 

Since the game has the tendency to crash quite often (once in 2 hours or 
so), I have to do this all over again because I found no other way to
get the sound right after the game crashed.

I'm going to try the OSS commercial driver (it helped me often with
sound problems in Linux games) but I prefer to use the pcm driver.

Any tips?

TIA,
Karel.
