Hello Jan, > Opening a playback stream with sample specification 's16le 1ch 8000Hz' and > channel map 'mono'. playback is 1ch 8000Hz while your sink seems to be only able to do 2ch 16000Hz, maybe try to play samples which do not require PulseAudio to resample/remap? > sample spec: s16le 2ch 16000Hz > channel map: front-left,front-right > Stereo check /et/pulse/daemon.conf, I have issues with default-sample-rate and alternate-sample-rate; I need to set both to the same value (which would be natively supported by your hardware, probably 48000 or 16000) turn on logging, start PulseAudio with pulseaudio --system --log-level=debug --log-target=stderr regards p. -- Peter Meerwald +43-664-2444418 (mobile)
