[LAU] Tascam US-122: No playback channels

[Michael Jarosch]

Hi!

I tried to make a Tascam US-122 "Classic" work with my
Debian-testing-powered Thinkpad T410. I followed the instructions on
https://alsa.opensrc.org/Tascam_US-122#Tascam_US-122_on_Debian_and_Ubuntu
as far as I could (alsa-base is not in Debian, anymore) but once I tried
to use the device for playback in pulseaudio I realized there was no
sink created. Pulseaudio offers the possibility to use the TASCAM with
"multiple input" besides "stereo input" (although I thought it's a
stereo in/out device) but there was no option to use it as an output.

I tried to use jackd to double-check the missing output, but it failed
to startup. Reason: "cannot configure playback channel"

The whole log (of the important part):

"jackdmp comes with ABSOLUTELY NO WARRANTY

Any ideas?
