[Thinlinc-technical] multiple and/or non-default sound card in terminal

[David Edmondson]

Is it possible to control which of the ALSA discovered sounds cards in a
thinlinc client is used by the thinlinc server?

I've built a simple Debian Live based USB image with the thinlinc client
(more about that at another time). It boots to X with the thinlinc
client running. This all works fine.

On one terminal I have two sound devices - the built-in HDA Intel and a
USB sound device. The terminal kernel discovers both, but only the HDA
device is visible to Pulseaudio applications on the server. If I disable
the HDA device in the BIOS then no devices are visible on the server - I
end up with 'dummy output'.

When both devices are present, the HDA is 0 and USB is 1.  When the HDA
device is disabled the USB device is still numbered 1.

My preference is to use the USB audio device as the built-in device is
susceptible to noise from other components in the system.
