Fix for audio pause bug when using passthrough on Linux - VladtheImpaler - 2024-06-12
I've had a long term problem with Jellyfin Media Player on pipewire. When passing AC3 or DTS over spdif and pausing a video, it would cause audio to start looping the last sound played over and over really fast. It was truly annoying.
It did with every version I tried, the Deb version, the Snap version, the AUR version, the Copr version, building it myself.. It did it on both of my receivers, 1 new Onkyo and 1 old Harmon Kardon. I did it with multiple audio devices, the Soundblaster Z and AE-5 Plus and the Realtek 892 and 1220.
The fix is to change pipewires period-size and headroom. I've confirmed the fix works on 3 different PC's. It's possible lower settings will also work, but I'm leaving them at 1024 and 8192 until I encounter problems.
Wireplumber 0.5 and newer
create: ~/.config/wireplumber/wireplumber.conf.d/50-alsa-config.conf
add:
monitor.alsa.rules = [
{
matches = [
{
## Matches all sources.
node.name = "~alsa_input.*"
}
{
## Matches all sinks.
node.name = "~alsa_output.*"
}
]
actions = {
update-props = {
session.suspend-timeout-seconds = 0
api.alsa.period-size = 1024
api.alsa.headroom = 8192
}
}
}
]
Wireplumber older than 0.5
sudo cp -a /usr/share/wireplumber/main.lua.d/50-alsa-config.lua ~/.config/wireplumber/main.lua.d/50-alsa-config.lua
Scroll to the bottom and change: (remove -- to uncomment)
["api.alsa.period-size"] = 1024,
["api.alsa.headroom"] = 8192,
--["api.alsa.disable-mmap"] = false,
--["api.alsa.disable-batch"] = false,
["session.suspend-timeout-seconds"] = 0
},
Reboot or restart wireplumber
systemctl --user restart wireplumber
