There seems to be a bug that breaks using the Tascam US-122 (with JACK at least) with any kernels newer than the 3.6 series. If this is going to be fixed, somebody needs to hunt down the specific change that caused it. The breakage happened between 3.6 and 3.7-rc1, so it will take about thirteen test kernels to find the offending commit. I'm willing to do the git bisect and the kernel builds, if somebody (or somebodies) will help me out with some testing.
Please note: These are pre-rc1 kernels, so there will be bugs. YOU HAVE BEEN WARNED!! I won't upload anything that I haven't first booted on my system, but there are no guarantees beyond that.
How you can help:
If you have a US-122 that works on an existing installation of AV Linux, and would like to test, here's how it works:
1. Install the most recent 3.6 testing kernel (posted in this thread), and boot into it.
2. Try to start JACK with your Tascam US-122.
3. Reboot into your normal stable kernel.
4. Post here with your results (working or not working). Please include the output of 'uname r' on the testing kernel with your results.
As soon as I get a working / not working report on a kernel, I can proceed with the next build.
Here's the first git bisect build:
