True, but I doubt that laptops have an open lid angle sensor. But this angle is usually around ~110 degrees, so it may be a constant for the initial implementation.

It looks like a kernel driver issue. Attach `dmesg`, but it will be probably better to continue on `[email protected]` mailing list.

This report is that syscall times are too big. It's unacceptable and it's causing issues, because pipewire operates with the data streams in one real-time thread. So if one or...

It's was tested without pipewire - just aplay. But it's HDA machine not soundwire like yours. I think that there may be a difference.

Thanks @ujfalusi . It seems like related to specific hardware. I'll try to do some debugging on my side. Any hints for more verbose printks between the code showing the...
