hi Ross, here I have the output of aplay -l
aplay -l **** Liste der Hardware-Geräte (PLAYBACK) **** Karte 0: SB [HDA ATI SB], Gerät 0: ALC892 Analog [ALC892 Analog] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 1: HDMI [HDA ATI HDMI], Gerät 3: HDMI 0 [HDMI 0] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0 Karte 2: UR22mkII [Steinberg UR22mkII], Gerät 0: USB Audio [USB Audio] Sub-Geräte: 0/1 Sub-Gerät #0: subdevice #0 As you can see, UR22mkII will be recognized. But only one channel - here 0/1. This results in : I can only use the output, NO Input is available. The same behavior I see in jackd - only the output can be reached/handled. Maybe, there is a configuration-possiblity in the alsarc-file ? Have tried out to set the output "by hand" but up to now with no success. The only functioning ouput is directly Input from Guitar to UR22mkII and from there to the amp but not to PC --> jackd, or audacity anything else. The messages from jackd lists as follows : Wed Nov 11 15:29:01 2020: Starting jack server...

Bitte sehen Sie im Meldungsfenster nach weiteren Informationen. Cannot connect to server socket err = Datei oder Verzeichnis nicht gefunden Cannot connect to server request channel jack server is not running or cannot be started JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock in my opinion there maybe either a hardware- or a driver-problem. Possibilty the missing driver for the yamaha.chip in the UR22mkII ? bye hans -- ubuntu-studio-users mailing list ubuntu-studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
