1 year ago @RustyClanker Can you clarify this
If I start up speaker-test and send audio only though the left channel, there is a consistent 1 second gap in the sound output (plays for 1 second, silence for one second). If I do the same through the right channel, the output is constant with no issue. if you use 'speaker-test -Dhw:0,0 -c2 -r48000 -FS16_LE -t sine' you'll get sine wave playing for one second on left and one second on right. That's the point of speaker-test, to make sure we hear what speaker is used.
From your description I wonder if it's actually the right speaker that's problematic and playing both L+R

This issue has been plaguing me for a long time, I have scoured the Internet and can not find anything related or a solution that works. I have stripped the sound system down to just ALSA with the raw driver outputs (no Pulse, no Pipewire, no JACK) and the issue is still present. I can plug headphones into the headphone jack and the issue is not present. I have been very hesitant to open an issue on this, but I have run out of stuff to dig into or try.
Retasking of the pins does nothing, shutting off power save does not correct the issue, using legacy drivers vs SOF does nothing, looping a silent sound in the background does not fix it.
There is a delayed start to audio if sending through both left and right channels, as long as the sound stays constant (through both channels) it will plays without issue. Once the sound stops, after a few seconds the delay will happen again. This is not related to powering save or idling, as disabling either does nothing to correct it.
If I start up speaker-test and send audio only though the left channel, there is a consistent 1 second gap in the sound output (plays for 1 second, silence for one second). If I do the same through the right channel, the output is constant with no issue. Using the GNOME control panel and doing a sound test, either Front or Left or Front or Right is cut off or there is a cut in audio in the middle of one of the words. I believe where it is cutting is related to the timing of pressing the test button in relation to when the test button was pressed in previous tests (pressing it right away after the audio stops or waiting a few seconds).
If a put a constant audio stream up (I was using random music from soundcloud), and move the balance toward the left channel, it starts the 1 second gap interval not quite all the way to left on the slider.
At this point, it is either the hardware or the driver. Audio in Windows works without issue (left and right channel play audio with no gap interval). Booting into Windows and then back into Linux does not fix the issue. It also happens regardless of the distro, Ubuntu, Pop_OS, Manjaro, Endeavour, Elementary, Debian, and ones I've forgotten. I think the only one I didn't try was Fedora.
Right now I am using a fresh install of Manjaro, all of the below is with Pipewire running using wireplumber as the media session manager. Again, it running has no bearing on the issue, I can turn it all off and the issue persists.
6.5.11-1-MANJARO thesofproject/sof#1 SMP PREEMPT_DYNAMICLet me know if anything else is required.
Thanks!
