alsa-project/alsa-plugins issue #21 was edited from davidebeatrici:
I originally encountered the issue ~1 year ago, when I started using a motherboard with an ALC1220 on it.
The out-of-box experience was flawless: I simply connected the optical SPDIF cable to my amplifier/receiver and stereo sound immediately worked.
Once I switched to 5.1 surround, audio output became extremely fast; even videos were affected by it, to the point that they were being reproduced in seconds instead of minutes.
After a few days of research and experiments I managed to workaround the issue by replacing the content of `60-a52-encoder.conf` with: ``` pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 card $CARD } rate 48000 } } pcm.pulse { type pulse } ctl.pulse { type pulse } pcm.!default { type pulse } ctl.!default { type pulse } ```
Based on https://help.ubuntu.com/community/DigitalAC-3Pulseaudio#Configuring_asound.c....
After that, I wanted to investigate the cause and report my findings to either ALSA or PulseAudio (depending on the results).
Unfortunately that never happened and I kinda forgot about it, as [libasound2-plugins](https://packages.debian.org/bullseye/libasound2-plugins) was updated a single time in the past year and thus I only had to replace the file's content once more.
Fast-forward to today: I switch from PulseAudio to PipeWire and while troubleshooting https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1143 I decided to try to restore the original file.
Interestingly, the behavior is different compared to PulseAudio: audio, instead of being fast, is crackling. It's basically as if a frame every two is being skipped.
Unfortunately PipeWire reports no errors whatsoever.
