I've been struggling for the past week to get a Tascam US-122 working in Debian unstable, and the problems are endless. I've gotten to the point where the green "USB" LED is turning on, which indicates that the firmware is being loaded successfully. This is using the version of fxload included in alsa-utils 1.1.3-1 and the firmware files included in alsa-firmware 1.0.29. I'm using the udev rule:
Code: Select all
BUS=="usb", ACTION=="add", SYSFS{idProduct}=="8006", SYSFS{idVendor}=="1604", RUN+="/bin/sh -c '/sbin/fxload -D %N -s /usr/share/alsa/firmware/tascam_loader.ihx -I /usr/share/alsa/firmware/us122fw.ihx'"
SUBSYSTEM=="sound", ACTION=="add", ATTR{id}=="USX2Y", RUN+="/bin/sh -c '/usr/bin/usx2yloader'"

Bus 003 Device 003: ID 1604:8007 Tascam US-122 Audio/Midi Interface
I know the hardware works because at one point I was able to get audio out of the interface's headphone output from jack. It only worked for a single session. The next time I tried using it, the audio was extremely distorted (a known issue with this interface), and after that (I have no idea what the factor is that changed...), I ran into the situation I'm in now:
Running "aplay -l" from the root account, I get:
Code: Select all
card 1: USX2Y [TASCAM US-X2Y], device 0: US-X2Y Audio [US-X2Y Audio #0]
Subdevices: 0/1
Subdevice #0: subdevice #0
