Audio not working

[ktulhu2000]

Audio not working inside nspawn container. Therefore board not starting at all.
journalctl -u mod-live-audio .... says ALSA cannot open hw:0 (or hw:1, doesnt matter - I tried different cards, different PCs)

All works with pre-built iso.

[falkTX]

those hw devices need to be free and not in use. if you have something like pulseaudio or pipewire it is likely those are being used by them, you need to find a way to force them to be free for use.

[ktulhu2000]

no no no. I didnt do anything.
This is how brand new created live usb stick works now after compiling.

I faced it before with the same picture. Alsa worked on host. But didnt work inside container. Even if I passthrough /dev/snd to it.
aplay -l gives no audiocard found (I copied agetty inside mod-os and was able login to shell with machinectl)
Assume there is some conflict between buildroot 2016 and archiso (wich is newer now)

[falkTX]

ah so you were always trying with the ISO. do you mean that your own created ISO does not work but the one from github action does?

I tested things locally (no ISO) in Debian 12 which is recent-ish, and got audio to work there.
Have not tried with the latest ISO builds yet.

[ktulhu2000]

Oh, ok!
Yeah, that was iso.
I will try to do it with debian. Seems I understand better now how everything works -)

I tested things locally (no ISO) in Debian 12 which is recent-ish, and got audio to work there. Have not tried with the latest ISO builds yet.

I've tested the released iso (v8) and it worked, but the one from the latest build from today (Custom empty pedalboard #132) didn't load the pedalboard, I've tried twice. I have a USB Presonus Studio 26c, tested on a Ryzen 5900X with 32Gb RAM. The soundcard is recognized perfectly but I can't go lower than 128 samples at 48Khz, the sound after that goes metallic and robotic, I don't know why. Is there any log I should check from the terminal regarding the V9 ISO issue?

[raidolo]

I can confirm that with the ISO the mod-live-audio.service has some issues.
I've built the ISO from a working local instance on my newly installed Debian 12. Locally it works, I can start the pedalboard and play any plugin.
In the ISO it seems that alsa could not open the hardware device properly.

I had the chance to save the full log of the mod-live-audio.service restart. Here it is:

Hope this helps.
Let me know if you need some tests.

Hey @raidolo, did you try to build https://github.com/moddevices/mod-host and https://github.com/moddevices/mod-ui on your system directly? I had more success with this approach than going with the iso.
Worked for the Raspi4.

I have no issues in building the UI and the mod-host from this repo, I didn't build them cloning the repos you mentioned, but the thing is that starting manually everything on Debian 12 from the mod-live-usb they just works. I still have issues when trying to go at 64 samples, the audio stutters and it's unusable and I still didn't figured it out, I don't know if it's something going on with alsa or it's jack that simply can't go that low. I dunno. At first I though it was the Presonus 26c, but I have the same issue even with my Mooer GE 250 at 44100khz and 64 samples...

Anyway, thanks for pointing me to direct repos, I'll try them...

Hi, I've tried to build the two components, but mod-ui doesn't see any plugin. I'm missing something.... any hint?

EDIT: Ok I've found that I have to put ther lv2 in /usr/lib/lv2 on my Debian host. My bad.
