This may be my first english entry here, yet it's quite needed because it's concerning a wide range of people.
To say it in short:
If you're using Linux and wanted to have hardware mixing capabilities in your soundcard, you always thought a card of the "Creative Labs - Soundblaster Live!" series would do the job. WRONG!
There's the "SB Live! 24 Bit 7.1" and the "SB Audigy LS" that have the CA0106 chipset instead of the EMU10k1 or EMU10k2 chipset. The CA0106 is more like a crippled down version of it and it supports NO HARDWARE MIXING. I repeat, NO HARDWARE MIXING.
Here's what my recent research on it gave to light: http://music.columbia.edu/pipermail/linux-audio-user/2005-February/020577.html
Well, of course, Creatives website says nice stuff like: "superb quality" and "hardware accelerated sound" and whatnot. You can give a shit about that concerning the above two soundcards. Remember, the soundcard is not an old model! It's still "new" and selling on the market.
Every cheap and old 10 Euro soundcard with the EMU10k1 chipset can do that! This "SB Live! 7.1" is not worth the name of "Soundblaster Live!" - really. And you can quote me on that.
So, talking about Linux, the site:
http://www.alsa-project.org/alsa-doc/index.php?vendor=vendor-Creative_Labs#matrix
... says, "Yo, ALSA supports this card" - ok, that means, ALSA can access the card and may mix soundstreams together ALSA-internally. Like the Windowspeople know it from DirectSound - The software mixes the streams together if multiple applications want to access the soundcard that has no hardware mixing capabilities. This results in a bit of "selfmade" latency since the mixing is done by the software.
But, there are still many Linux applications that only support the deprecated OSS "interface" and thus lock other applications out if it already uses /dev/dsp. If that's the case, YOU NEED the capability of mixing soundstreams in the soundhardware to allow those applications to co-exist.
Nevertheless, it's clear, such applications should finally update their software to use ALSA.
TeamSpeak, in its Linux version, is one of those applications .. funny enough they make money by licensing TeamSpeak servers to resellers but have not managed it since three years to release an ALSA version of TeamSpeak. Goto http://www.goteamspeak.com to have a word with them.
So what I wanted to say:
- Screw Creative Labs because of the standard they lowered and thus sell crap.
- Screw applications that still have no ALSA support.
Look at cool games like Doom3. It definately has ALSA support and that's the way to go. Still, keep away from the CA0106 soundcard chipset of Creative.
So.. good night
