Re: Bug in Alsa Driver 'snd_soc_sst_bytcr_rt5651'

"piiiiiiiiiinnnggggg" or "beeeeeeep"? (pure sinus)

Do you get that PA message whenever and everytime you hear a "piiiiiiiiiinnnggggg"?

Play video with what?
Does

mpv -ao alsa someporn.mp4

cause the same artifact?

And to be sure: you did try to play someotherporn.mp4 to ensure that the noise isn't actually part of the audio stream?

I was playing it with mpv

gnome-session-inhibit mpv --hwdec=vaapi video.mkv

I tried other video as well, but the problem persists.
When the weird sound (piiiinnnggg) comes , video gets paused, and even if i kill video/mpv sound last for 20-30 secs

Now I did

pacman -Syu

ucm files got updated. Though I still get same message when trying "journalctl -p3 -xb" (without core dump this time), I didn't hear that weird sound while playing the same video.

Re: Bug in Alsa Driver 'snd_soc_sst_bytcr_rt5651'

The message can be normal and is generally ignorable and has been downgraded to debug in the next pulseaudio release, this was likely fixed by the new ucm config.

Re: Bug in Alsa Driver 'snd_soc_sst_bytcr_rt5651'

Hello,

I have a very similar problem. After few tens of seconds of playback, the sound output only emits a long beep.

I reproduced the problem with mpv (video or audio only) and firefox (youtube) and it happens with pulseaudio or pipewire-pulse as well.

All my packages are up to date and latest ucm did not fix it. When using pulseaudio, the "bug in Alsa Driver 'snd_soc_sst_bytcr_rt5651'" is present in the log, but no additional message is printed in the journal when the beep occurs. My laptop is an Asus T101HA
