Pulseaudio start sink on startup/login
Pulseaudio start sink on startup/login
I use DisplayPort audio as my main output, and it seems there is a slight delay between the sink being started and me actually hearing anything (the audio isn't delayed I just miss the start). I've managed to mostly fix it by disabling suspend on idle, so now once I've played some audio once its fine.
However when I reboot I then miss the first bit of audio again. I have no idea what I need to do to fix this. If I try to manually enable the sink with with pacmd suspend 0 I still get the same issue. The only potential fix I can think of is to set a KDE startup command for pacmd play-file and point it to a very short silent audio file. Does anyone have any better ideas?
Edit: I forgot to mention, when suspend on idle is enabled there is an audible pop every time the audio starts and suspends. With suspend on idle disabled I still hear this pop on login (and the first time audio is played) which suggests something is happening when I log in
Edit 2: Apparently it still does it every time the audio stream switches to a different app, however if I start the second one playing before I pause the first it starts straight away
Does that happen on PipeWire too? In my experience it's a lot more reliable and has a much better internal design.
I just tried pipewire but it didn’t make any difference
I have noticed this too on pipewire. Everytime a new audio stream starts , even from a paused state, there is a small delay before it is heard. Not a syncing problem as the audio is synced, but a delayed start. I thought it might have something do with the sound bar I had routed the audio through. Based on your experience, seems not. I did experience the same delay when using HDMI port instead of DisplayPort too (IIRC). So it might be something else not related to port.
Interesting, how is your sound bar connected?
Initially, I used HDMI -> Soundbar -> Monitor. The soundbar handles the sound and forwards the video signal to the monitor. Right now, it's the same, except it is using display port for Laptop to Soundbar connection. Hope I understood the question correctly. If you ever figure out the delay, please do update with a solution.
