With ALSA, you have to use hardware which supports hardware mixing of PCM channels. Examples include: Yamaha Waveforce 192 XG Yamaha Waveforce 192 Digital Turtle Beach Santa Cruz Trident 4DWave DX/NX Creative Labs Soundblaster Live series Cards with the Cirrus Logic CS46xx chipsets See http://www.alsa-project.org/alsa-doc/ for a more complete listing. If you're willing to use the commercial OSS drivers, I believe they include software mixer. This of course means higher CPU utilization, but depending on your purposes, may work out quite well. -- Steven Yap <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
