[PlanetCCRMA] Problems with TASCAM US-122

[Martin Visser]

Thanks for that. So does PlanetCCRA have a regular CVS snapshot
kernel+alsa that is built nightly - or do i have to build it myself. I
noticed from the ALSA site there is zillion ways to patch alsa - I am
wondering what is the best way to do this with a PlanetCCRMA system.
