sound sequencer is missing inside fexbash

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:

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

built it from main branch 1h ago :)

[kocou-yTko]

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]

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]

@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]

@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]

@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)
