5.1 Surround with ALSA and OpenAL. [ALSA VoIP added]

Okay the new ebuild is up, but note, when I released the one on the 17th, I screwed up and named it 20040317, instead of 20040217. If you used the ebuild from two days ago when you update to todays it'll think it's downgrading, don't worry, it's not.

Okay guys, Warp/Mercury got cvs access and merged some of his changes into cvs, so patch no longer applies. I'll update the ebuild right now.

Edit: http://floam.ascorbic.com/gentoo/openal-cvs-20040221.tar.bz2

Also, Mercury has confirmed that the ALSA VoIP now performs better than OSS! (as far as choppiness and how it scales at low fps)

for some reason, the sounds in UT2004 now sound extremely sped up. ;\

i've set my .openalrc file exactly the way you have it in the guide (i have a 5.1 surround sound set), plus i soft linked the libopenal.so file from /usr/lib to the system directory of ut2004.

maybe my problem is, that i only have 4.1 and no surround?

Merc: I'd reccomend you to read http://icculus.org/~warp/ut2004 and try a few of the things it wants you to do, notably the libsdl stuff.

sweet... it works perfectly now. thanks

oh yeah... how did you have the sound coming from all 5 satellite speakers? im wondering how to get that to work as well... only works out of 4 for me (which i assumed is the correct way for it to be since .openalrc defines it as so, but it seems like you got it working out of all 5).

i only have mic boost and audigy analog/digital output jack on. when i turn off the digital/analog output jack, there's absolutely no sound.

floam · Posted: Sat Feb 21, 2004 10:14 pm Post subject:

OpenAL doesn't support more than four speakers, but ALSA should make Center and LFE get sound. Turning off the Digital/Analog output jack causes the rear speaker jack to output in analog. I wonder, are you getting discrete sound out of your rear speakers with it on? (Test by shooting a rocket at a wall, and turning around really quick, you should hear it from rear speakers since the explosion is behind you)

yeah... each channel sounds seperate from each other.

only problem is that the sound doesn't output to my center speaker, nor does it output to my headphones connected to my audigy 2 frontplate.

with a sound blaster live! (4.1, non-surround) you can't get surround sound. maybe there IS a way to emulate it for games. i think it works in windows, but i've never really tried that. altough there are is a "surround" lever in alsamixer, it really only mirrors the front speakers. i've tried all kind of possible settings without luck. without the "surround" lever you won't get anything out of your rear speakers. the "wave surround" does virtually nothing to games, but enhances my rear sound, if i'm listening to music.

maybe it's time to get another soundcard. i had a audigy 2 a few weeks ago, but it made only problems (more so in windows, than in linux) and before i sent it back it crashed my pc, before i could even get to my bootloader. audigy 2 is by far the worst sound card i've ever had. i'm very disappointed with creative.

Updated ebuild with a new patch from Mercury. (Supposed to make velocity and pitch work, might raise sound quality.)

http://floam.ascorbic.com/gentoo/openal-cvs-20040304.tar.bz2

Also updated the guide a bit to mention replacing libsdl.

Okay, updated again, there were some changes in cvs so a new patch was required. http://floam.ascorbic.com/gentoo/openal-cvs-20040314.tar.bz2

This guide is pretty much obsolete. People with Creative cards should go read the Hardware Accelerated OpenAL post.
