[PlanetCCRMA] SIIG-USB SoundWave 7.1 Pro

[John Dey]

Hi Fernando,

Thanks for your response.  The output from the 2 commands are shown 
below.  I should mention that the soundcard has two female jacks: one 
for audio out and the other for mic in.  The audio out has two uses: 
for headphones or for a spdif output cable (optical) that I am 
attaching to a audio receiver.  It is my understanding that that cable 
should carry the 7.1 signal.  When I plug in headphones to receiver 
directly, I hear stereo.  When I plug in the spdif cable and listen to 
the headphone jack on the audio receiver I hear stereo.  I don't have 
speakers connect since they have not been delivered.

John
