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!
