usb-audio problem
#1
Good evening


A short introduction to tell the community that I'm using the tinkerboard since 6 months for an astronomy project.
The TB is piloting my telescope, APN, GPS, CCD and other devices.
So far so good except that I'm now considering to install a radioastronomy module (RTL-DSR based) and that I woul like to get some audio but i does not really work no to say at all.

Configuration:

Ubuntu-Mate 16.04 / Core Linux 4.4.166

Issue with audio:

pavucontrol doesn't shown the usb-audio but only the HDMI audio.

command: sudo alsa force-reload

alsa Unloading ALSA sound driver modules:.
Loading ALSA sound driver modules: (none to reload).

The command lshw shows the usb-audio rockship hardware as being detected.

This problem has been reported several times but reading the forum did not help me so far.
I really need so help to make it works as I already spend some hours and I'm almost getting nervous :-)

Thanks to help
