Hi, Ah!Oh! Yes...I see...sorry for my blurred view to this problem. Yes, I am trying to use jackd with mpv, whcih leads to this error. My setup is: jackd, alsa mpv After stopping jackd I can play the track with mpv...so alsa as such seem to be well and up running. Enabling jackd again shows this (this time I will post the whole thing ... so nothing is censored by me... ;) File tags: Artist: Unknown Album: Unknown Disc Genre: Alternative Title: Track 02 Track: 2 ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.0.29/work/alsa-lib-1.0.29/src/pcm/pcm_dmix.c:1024:(snd_pcm_dmix_open) unable to open slave [ao/alsa] Playback open error: Device or resource busy AO: [jack] 48000Hz stereo 2ch floatp A: 00:00:09 / 00:11:54 (1%) BUT it plays this time... Do I have kill jackd, play something with alsa, restart jackd and it "works" ... ? Sounds silly...but at least "it sounds". What's going on here? Best regards, Meino
