So no simple explanation for why that failed. Is there an environment variable or command line option to give to cause verbose backend debug information to be printed? This is the network audio driver from Merging, running in AES67 mode, to a device which only supports 48 sample frames in AES67 mode, so will probably be a challenging configuration no matter what. I believe the Windows equivalent drivers have additional buffering so that on the user space side the applications can use larger buffers, and the kernel driver breaks the larger application buffer down to the smaller network buffers. That would be useful for this driver as well, but first step would be to at least get Ardour running at all, even if with xruns. The driver does work with aplay and mpd, so non-pro type apps are working, but not Ardour or jackd. I will gather more debug output this weekend, maybe something will give an indication why the fallback to interleaved is not working. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
