[gentoo-user] Sound with Virtual Channels

[gentoo-user] Sound with Virtual Channels

[Greg Armer]

Good day list,

Does anyone know what I can do to achieve the same effect in gentoo that
I get when using "sysctl hw.snd.pcm0.vchans=4" in FreeBSD, thereby
allowing 4 virtual channels for my dsp device, and stopping those
annoying "Device in use" errors when trying to open 2 or more sound
related programs.

I have searched the mailing lists, google and the forums and have found
nothing.

I am using Gentoo 2005.0 + esound

Thanks for any responses

Greg

Recent ALSA versions do softwaremixing using the DMIX plugin per 
default. Older versions can do it by creating an soundrc file.

Unfortunately this does not help with legacy applications which still 
use OSS or the ALSA OSS emulation - like Skype or Realplayer do :( .


Best regards

does that mean that OSS emulation does not use dmix?
