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
Are you sure your speakers aren't powering down after a delay without input? You might be able to solve this issue and the popping with better speakers.
It’s just the inbuilt audio in my monitor. It doesn’t do this with any other device plugged in or with my PC when it’s running Windows
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.
I'll let you know if I find anything, I've just posted on the Arch forums as well so hopefully someone there can help. If not then unfortunately this one might stay unsolved
I’ve found a janky fix that seems to work. I noticed that if you start a second audio stream while the first one was still playing it started straight away. There is a pulseaudio module called module-sine which generates a constant sine wave and you can choose the frequency.
So I added load-module module-sine frequency=1 to /etc/pulse/default.pa. This constantly plays an inaudible sound wave which seems to keep the stream alive and stops the popping/delays. I’m not 100% sure if that is a good fix or not as you are effectively constantly playing audio, but I can’t find a better way to solve it!
I guess that's one way to fix it. Thanks for letting me know.
However, I think I will keep searching for a different fix. Playing a sound constantly will keep on nagging me, even though it shouldn't. Also I am worried about what will happen when an application like mpv wants full access to the device, but there is an ongoing stream there.
On a side note, since this came up and I have been paying attention, I noticed that some of the system notification sound that I keep missing are caused due to this delay :(
On the plus side, since I almost constantly listen to some music at low volume, I might actually be doing your fix in a round about manual way. This was how I noticed that system notification played fine, if music was already playing, but not otherwise.
One other suggestion I saw was to create a file under /etc/modprobe.d/disableHdaPowersave.conf with the content options snd-hda-intel power_save=0, but that made no difference to me. If you do find anything else please let me know as I'm not 100% happy with my solution!
Thanks, but that didn't make any difference for me as well. I will let you know if I find anything else.
