alsa-project/alsa-plugins issue #37 was opened from sjnewbury:
Using the lastest code since v1.2.5 I can successfully get AC3 output through HDMI when using speaker-test. Defaults uses a huge buffer and gives terrible latency, but it works.
PulseAudio also works fine with fairly low-latency using "tsched=1 tsched_buffer_size=32768 tsched_buffer_watermark=8192 fixed_latency_range=yes mmap=1". This doesn't need the rate kludge any more.
When I try pipewire using mmap I get the below messages in the log, no audio:
`spa.alsa: alsa-pcm a52hdmi: mmap_commit wrote 512 instead of 1024`
With mmap disabled, no errors are reported, but still no sound.
Is there a configuration for pipewire which works with the a52 plugin, a pipewire bug, or is this another a52 plugin bug?
