It solves the problem for apps which want to access the ALSA device (HW:0 etc.), but as soon as an app tries to get OSS access via /dev/dsp DMIX cannot do softwaremixing. Maybe I'm wrong, but AFAIK such apps need to be started with the aoss wrapper. And no user starts mozilla as "aoss mozilla", does he? > but it seems like it's > not that easy to set it up (I haven't tried since I have > soundcard with hw support for multiple channels). AFAIK the latest ALSA and kernel brings DMIX per default without the need to create an asoundrc. Best regards ce
