Hi list, I am replying to my own thread (see below), which is still unsolved as of today. I investigated further and experienced the same issue with an identical second Edirol UA-24 soundcard on an identicel second X230 Thinkpad with jackd2 on Debian and am experiencing the same jackd2 lockups. However when using a Roland Rubix24 interface for comparison, jackd2 suspends and resumes fine. Still looking for any pointers how to debug this further, which are much appreciated! best, Peter * Peter P. <peterparker@xxxxxxxxxxxx> [2024-01-24 11:16]: > Hi, > > Running jackd2 on an Edirol UA-25 USB interface as > jackd -t2000 -dalsa -r44100 -p512 -n2 -Xseq -D -Chw:UA25 -Phw:UA25 -i2 -o2 > I can not get clients to connect after having resumed the computer from > "systemctl suspend". > > Upon resuming, jackd reports > status error: No such device > ALSA: channel flush for playback failed (No such device) > JackAudioDriver::ProcessAsync: read error, stopping... > and hangs. > > Trying to use mpv or puredata with this locked server then throw the same messages: > > Cannot read socket fd = 13 err = Success > CheckRes error > JackSocketClientChannel read fail > Cannot open mpv client > JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock > JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock > JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock > > Nevertheless, qjackctl indicates a running server but throws > Cannot create new client > JackPosixProcessSync::LockedTimedWait error usec = 5000000 err = > Connection timed out > Driver is not running > Cannot create new client > > journalctl/dmesg show that the USB sound card is discovered as a new > device after resuming from the suspend state. > > Stopping the server takes some time then, throwing: > ALSA: channel flush for playback failed (No such device) > Cannot stop driver > port deleted: UA-25:midi/playback_1 > port deleted: UA-25:midi/capture_1 > Released audio card Audio2 > audio_reservation_finish > 11:05:51.251 JACK was stopped > > This problem does not exist when using jackd1. > > The computers internal soundcard (intel-hda) survives resuming from > suspend with jackd2. > > What can I try next? > > Thanks! > Peter _______________________________________________ Linux-audio-user mailing list -- linux-audio-user@xxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to linux-audio-user-leave@xxxxxxxxxxxxxxxxxxxx
