No Audio after update to matrix

[mrVazil]

Hello, after updating my Vero4K to the new August update I lost audio output. Setup is Vero4K HDMI attached to TV, no other devices.

I only see pulseaudio in my Kodi Audio settings. HDMI and other things have disappeared.

Here are logs after fresh reboot and test playing a couple of files… one 5.1 and another 2.0, and also a video plugin.

Pulse is deprecated, check the bottom of this first post

[How-to] set up Bluetooth audio

[Updated November 2021] Bluez-alsa allows you to stream audio both to and from your OSMC device. We have now integrated bluez-alsa into OSMC as a replacement for our a2dp package which is deprecated. Our Kodi v19 builds include bluez-alsa. If you are still on v18.9, you can install it on Vero 4k or RPi 2/3 with: sudo apt-get install armv7-bluezalsa-osmc and re-boot to get the bluealsa service started. If you have previously installed one of our older BT audio packages, you will need to re…

Thank you, uninstalling pulse audio fixed the issue!

For me, uninstalling pulseaudio at least fixed the “kodi has no sound at all” problem, but created other problems:

1. audio streaming from my desktop PC that had relied on pulseaudio doesn’t work anymore, obviously.
2. raspotify doesn’t work anymore. From what I can see the problem seems to be that the alsa audio driver of the AMLogic S905D reports false max/min buffer lengths that it does not actually support. This was apparently mitigated by pulseaudio before. The librespot people have implemented a workaround, but it’ll still take time until it appears in raspotify packages. ERROR ALSA function 'snd_pcm_hw_params_set_buffer_time_near' failed with error 'EINVAL: Invalid argument' on playback on Vero4K · Issue #895 · librespot-org/librespot · GitHub

Are there any plans to transition to pipewire?

No. If we are reporting unsupported buffer lengths, we can look into that.

I‘m so glad I found OSMC.
It seems as if all other Linux distributions for the Raspi use Pipewire now, which makes them useless for KODI. I’ve tried everything, bit bitstreaming went impossible, so my big Dolby Atmos library can’t be played anymore.
OSMC works like a charm!
Please stay away from Pipewire…
