I notice that the RME fireface alsa driver snd-fireface now works a little since 4.19 I think In earlier kernels 4.18 and below the midi worked on the FF400 but no audio and the FF800 was not supported at all. now the midi works on both FF400 and FF800 and the audio works a little. the kernel I am using is 5.0.0-7.1-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.0-6ubuntu1~bionic (2019-04-06) x86_64 x86_64 x86_64 GNU/Linux (I am also happy to test with a different kernel but I am not able to compile it myself so it would need to be available in a repo.) The audio however does not work correctly. It is unstable, sometimes it works for a while but other times it glitches or even becomes wildly distorted. I am not a kernel developer at all - but I am willing to test and post logs if it helps - if anyone here can give me clear instructions about how to test. Also - is it possible for a user to disable the audio part of the driver but still use the midi part? This would allow me to use the audio with FFADO and the midi with alsa. FFADO doesn't support midi on these devices so it is great that alsa does - but running both at once can be tricky as the alsa driver does not let FFADO take over the device once it has it. Can I suggest that maybe the audio and midi drivers for these devices could be made as separate kernel modules? Then if one part has problems it need not be loaded. I'm not sure if this is feasible but if it is it would allow more flexibility in how they are used. thanks Thet _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
