[linux-audio-user] Disabling Playthrough

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Well my problem is that playthrough has been enabled, and I don't want 
it to be (or I should say, I want to have control over it).  I can't 
figure out where to turn this off/on.  All of the obvious system 
control panels don't seem to have a setting for this.  Using command 
line tools for ALSA, I don't see anything either.  I wouldn't expect it 
to be turned on by default.  I have been able to record audio in 
audacity, so samples are being passed up to the application.  Now I 
have a weird situation where audacity says that the audio i/o system is 
unavailable.  Playthrough is working... speaker-test works.  Various 
audio players are able to play CD audio and open and play sounds files.

Linux audio is a bit byzantine compared to what I'm used to... there 
appear to be several interacting layers, and control panels in various 
places.  If anyone has suggestions or pointers to a good 
linux-audio-howto or getting started that explains all of this, I'd 
appreciate it.

thanks,

darren
