[alsa-devel] External Sound Card

[John Dey]

Clemens,

Thanks for your response.  The 5.1 or 7.1 capability is not as 
important to me as having 6 or 8 independent jack channels  to connect 
4 or 8 channels from an application (ambiosonics from aeolus).  Without 
adding the a52 plugin would I see more than 2 outputs in qjackctl?  
With the plugin would I see 6 outputs?
