if midi traffic on one card causes jack xruns on another, that rules out
jackd, doesn't it? reason i'm asking is you suggested to try
alsa-lib/test/latency.c, and i have trouble understanding how to run it.
i get
kleineronkel:/local/build/alsa-git/alsa-lib/test # ./latency -r 48000 -P
hw:1,0 -C hw:1,0 -c64 --period 64 -f FLOAT_LE -s 10
Scheduler set to Round Robin with priority 99...
Playback device is hw:1,0
Capture device is hw:1,0
Parameters are 48000Hz, FLOAT_LE, 64 channels, non-blocking mode
Poll mode: no
Loop limit is 480000 frames, minimum latency = 64, maximum latency = 4096
Access type not available for playback: Invalid argument
Unable to set parameters for playback stream: Invalid argument
it seems to be hardcoded to SND_PCM_ACCESS_RW_INTERLEAVED, i guess that
won't work...
i changed it to ..._NONINTERLEAVED, but now i'm stuck at:
kleineronkel:/local/build/alsa-git/alsa-lib/test # ./latency -r 48000 -P
hw:1,0 -C hw:1,0 -f FLOAT_LE
Scheduler set to Round Robin with priority 99...
Playback device is hw:1,0
Capture device is hw:1,0
Parameters are 48000Hz, FLOAT_LE, 2 channels, non-blocking mode
Poll mode: no
Loop limit is 1440000 frames, minimum latency = 64, maximum latency = 4096
Sample format not available for playback: Invalid argument
Unable to set parameters for playback stream: Invalid argument
same issue with [US][16|24|32]-[BE|LE].
