Followed this guide and managed to install ableton live

After successful install I'm trying to run ableton, splash screen shows, init starts and then it fails due to error:

00e0:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.

I see that if I run aplaymidi -l inside vm I get

 Port    Client name                      Port name
 14:0    Midi Through                     Midi Through Port-0

But if I run it inside FEXBash I get same error when ableton fails

ALSA lib seq_hw.c:528:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
Cannot open sequencer - No such file or directory

That PulseAudio: Unable to connect: Connection refused makes me thing you're running a version of krun that doesn't include #9

but according to pull desc, ls $XDG_RUNTIME_DIR/pulse ls: cannot access '/tmp/krun-run-1000-OfDgwQ/pulse': No such file or directory

Perhaps you don't have the socat package installed on your system?

kocou-yTko commented 1 month ago

yep, installed it, same error like before about snd/seq

ALSA lib seq_hw.c:528:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
00e0:err:winediag:MIDIMAP_drvOpen No software synthesizer midi port found, Midi sound output probably won't work.

Looks like, within the FEXBash context,aplaymidiis not even trying to use pulseaudio. @teohhanhui does your guide instruct users to installalsa-plugins-pulseaudio` in the FEX root?

teohhanhui commented 1 month ago

@slp Oh yeah, it's actually necessary to remove pipewire in the FEX RootFS now.

EDIT: Updated my guide.

@kocou-yTko Do let us know if it works now.

kocou-yTko commented 1 month ago

@teohhanhui seems not but i'll try from the scratch a bit later because i'm not sure my previous tries before posting reddit doesn't affect anything

kocou-yTko commented 1 month ago

@teohhanhui yep, same. removed asahi-krun container, rootfs, etc and started from zero - now /dev/snd has the timer only, seq is missing, pcm devices missing too in FEXBash (pcms were present when issue was started)
