/dev/dsp can only be used by one process (8.1)

After finally upgrading from 8.0 to 8.1 i got my nforce/i810 audio card working, but now I have a unique (I think) problem. If one process ties up /dev/dsp NOTHING else can ever use it. When I start X I have gmixer run as an applet. With this running I don't get sound from XMMS without changing to the esound daemon. If I shut all sound-using processes in X down, and start XMMS using OSS it'll work, but if I then start GAIM or arnything else I get the error message that the resource /dev/dsp is busy. Any idea on this one guys? I'm using 2.4.18 patched for my nforce board, and for my GeforceII

You might consider switching to Alsa sound drivers. I haven't had problems with multiple sound events using alsa. They have the Intel i810 audio chipset listed as supported.

I'm still working on my sound set up (also wth the i810 architecture, integrated SoundMax), but my understanding is that the driver (OSS, Alsa, whatever) can only handle one process at a time. Thus, it is necessary to run ESD or aRts (KDE) to manage the different processes.

Helpful? Correct, anyone?

I figured out that if I reboot my system and start X *without* Gnome, then I can run all the games I want to with out any audio problems.
It is only when gnome starts first that the "/dev/dsp" resource busy error appears.

BTW I am running Wolfenstine & Quake on P4 2gig+TNT2 M64 RH 8.0 (with NVIDIA's latest drivers)

Yep I also have this problem, though I have compiled sound support right in to 2.4.19 kernel No changes, but offcourse sound quality was better than with OSS
