Hi Takashi, others,
Can we include my mixer control into the driver? I think it is important to include the clock source selector switch as an alsamixer setting. Every other serious soundcard allows clock source selection.
I tested 003R+ with Robin's suggestion of hacking the state to be statically initialised to zero (which won't work for multi devices), and the results were great: dead silence on channel 1 when playing into channel 18. This small hack means that Robin's update to 003amdtp should work flawlessly when integrated into the driver properly.
Takashi: I am also reporting that ADAT sync, SPDIF sync both work using my clock source selector control. In fact, without the sync to external device, there are many dropouts in the 1394 streams. How can we address this issue?
Regards, Damien
