Hi again,


I installed now an Ubuntu 16.10 (because this distro can handle ffado 2.3
well), and now almost work the playback (but sometimes a bit noisy, and I
dont know the reason).
When I start the FFADO Mixer from terminal, I get the following messages:

Cannot create RT messagebuffer thread: Operation not permitted (1)
Retrying messagebuffer thread without RT scheduling
Messagebuffer not realtime; consider enabling RT scheduling for user

(And if I close the mixer GUI, I cant re-open again without killing the
ffado-dbus-server)

Maybe should I - somehow - force the ALSA driver to keep always the 24bit
48000Hz?
Anyway on the mixer I use under the "Mix" tab; Stream 1/2 In.

Regards,

Peter
