I'm dual booting Trisquel on an old pc. It has an after market sound card in
it. When I run windows, the sound card can take a line-in signal and pass it
through to the 5.1 speaker system. This is kind of my main audio system at my
desk. If I'm working on my personal or work laptop, I just connect the
headphone out to the tower sound card and avoid using laptop speakers.
The problem occurs when I boot Trisquel. The line through functionality
doesn't work. I'm running xfce4.
$ xfce4-mixer
brings up the audio mixer just fine. In the sound card selection I can see
the Envy24. I can also see a "Built-in Audio Analog Stereo (PulseAudio
Mixer)" selection. So Trisquel sees the sound card.
Looking up drivers for the sound card, they are all for Windows.
It's tough for me to test if the sound card is working for audio originating
in the system since I don't have any media players or anything and don't know
how to generate a test tone in Linux.
Thanks for any help.
