Soundblaster Live + alsa + quake3

Peter · #1 16-01-2003, 23:34

Hi,

ok here is the story =). I've been running TeamSpeak fine on my SuSE distro, with the oss drivers. Now I installed gentoo, and decided to give alsa a go. Thats where to problems began.

TS and q3 using /dev/sound/dsp (standard)
TeamSpeak works fine, quake3 hangs on sound initialisation, if TS is running, else quake3 works fine.

TS using /dev/sound/adsp q3 using /dev/sound/dsp

TS doest work (in + out muted)
TSclient.log:
16-01-03 23:28:34,29655,ERROR,All,TOSSioThread.Initialize,E xception EOSSException: OSS error in OpenSoundDevice (/dev/sound/adsp): No such device
quake3 works fine

quake3 using /dev/sound/adsp, TS using /dev/sound/dsp

TS works fine, quake3 starts, but doesnt give any sound.

So, whats the deal, what am I doing wrong ??

common guys, dont give up on me please

I can't help you, but I've never can use ALSA and TeamSpeak (but I've read the FAQ on this forum). You say that you can use ALSA and TeamSpeak, I'm interesting in how you could do that, if you have any tips

Because the only solution that I have to use teamspeak and play => use OSS kernel driver for my sblive but I will do the max to can use ALSA !

NB : <troll> I use also the fabulous gentoo linux

this might work

Quote:

adsp is a play back only device. hence, you need to make games use it, and teamspeak to use the playback and record one. how i hear you cry ? -- do a symlink from /dev/dsp --> /dev/sound/adsp and /dev/adsp --> /dev/sound/dsp job done.

as I said in my post, using /dev/sound/adsp causes quake3 to stop issuing sound at all. Players like xmms or zinf also can't play on it....Dont know why that is though.

quake 3 uses the dsp thats then linked to adsp. yes?

Well, =)

luckily I asked the alsa experts not only you guys =). I got my problem fixed thanks to a guy there. In hope to aid people comming I will post the entire message here.

There's not an easy fix. This example shows exactly the broken API design
as OSS. We don't know at open time, if application requests the device for
read or write or duplex operation, so we assume that all directions are
wanted. There is no /dev/adsp device for EMU10K1.

Anyway, we have proc interface where you can tell to driver that only
playback is wanted. Try this:

% echo "quake 0 0 direct" > /proc/asound/card0/pcm0p/oss
% echo "quake 0 0 disable" > /proc/asound/card0/pcm0c/oss

Replace quake with real application name (use ps command to determine it
at runtime).

So, what I did was put those to commands (quake3.x86 instead of quake) in my local.start bootup script, and voila, now alsa knows that quake3 will not come along and request full duplex or something during runtime. Works fine !!

PS: emu10k1 doest have /dev/adsp

Did you get Quake3 and TS2 running on your sbpci128?
Allthough I have tested the mentioned method, too, there's no way to use one device twice.
That means I have still a problem with using both, a Quake3-engine game and teamspeak.
