I'm managed to isntall PD with aptitude and I wanna connect a MIDI device to PD, but something is messed up. I can play audio to a USB sound card with speaker-test, but still not open qjackctl. qjackctl says: Code: Could not open ALSA sequencer as client ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory And modprobe snd-seq gives: Code: sudo modprobe snd-seq modprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='snd_seq' modprobe: ERROR: could not insert 'snd_seq': Function not implemented modprobe: ERROR: ../libkmod/libkmod-module.c:959 command_do() Error running install command for snd_seq modprobe: ERROR: could not insert 'snd_seq': Operation not permitted Code: lsmod | grep snd snd_usb_audio 120998 2 snd_usbmidi_lib 18530 1 snd_usb_audio snd_rawmidi 19032 1 snd_usbmidi_lib snd_hwdep 5492 1 snd_usb_audio usbcore 200220 5 snd_usb_audio,snd_usbmidi_lib,ehci_hcd,usbhid,ci_hdrc Code: ls /dev/snd/ by-id by-path controlC0 controlC1 midiC1D0 pcmC0D0p timer Any pointers on fixing this? Thanks
