alsa-project/alsa-plugins issue #38 was opened from jensgw:
Dear Maintainer,
this bug was originally reported on the debian tracker. They advised me to post it here. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=998125
* What led up to the situation? Fresh Debian 11 install. I want to output 5.1 sound via toslink. Used KDE settings to switch from analog output to digital out 5.1. This produced no or garbled sound and Youtube videos would play back way to fast without sound. Then I switched to digital out stereo, this worked as expected but only stereo.
I could trace back the error to the shipped config file for alsa's a52 plugin: 60-a52-encoder.conf.
When I replaced that file with a much simpler one (see below) 5.1 digital out worked as expedted.
I tried with onboard sound (PCH9) and dedicated card (Audigy Z) with the same result, the inlcuded a52 config file does not work.
== Start a52.conf pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 448 channels 6 card $CARD } rate 48000 } } == End a52.conf
Therefore I assume the shipped config file with debian has an error somewhere. Please fix this.
Best reagards Jens
