 Posted: Tue Dec 16, 2003 4:34 pm Post subject: Full Duplex ALSA? |
 |
|
Why is it that I can only get one sound imput at a time with ALSA? For example if I'm using beep-media-player (OSS Output Plugin) and gaim (aplay command to play sounds) then only one can play at a time... and oddly enough all the gaim sounds que up and play after I stop playing music with beep.
edit:
I use:
gnome 2.4
linux-2.6-test11-love1
CMedia Internal soundcard (Gnome ALSA Mixer lists it as CMedia PCI)

I don't know anything about that chip, but I would check and see if it has hardware mixing, if not you will need to set up dmix (an alsa feature) to do software mixing.

Just fyi, duplex is when you can read from the soundcard and write to it at the same time, ie- you can be recording from a microphone and playing music at the same time*.
What you're talking about is mixing.
* - silly example. In real life the applications for this are far more useful/exciting. Think realtime audio processing. |
