Camiladsp 2.0 stop working on loopback ( 32bit os)

[melomane63]

Using CamillaDSP 2.0.0, pi zero W 2, Raspberry Pi OS lite 32bit ( latest or legacy ).

Camiladsp 2.0 stop working after somes seconds if input is on loopback ( hw:Loopback,0 ) this is the log out:

Work fine on 64bit os with the same .yml config file .

Can you please run this with trace log level and post the output, together with the full config file?

i hope this is what you want

Thanks! I see some of these lines: 2023-12-15 21:57:30.597097 TRACE [src/alsadevice.rs:274] Capture waited for Some(39.145833ms), ready 39 ms is about twice what it should be. It looks as if sometimes the event that signals that the loopback is ready goes missing. There have been similar issues before, and if I remember correctly it seemed linked to then the CPU governor adjusted the CPU frequency. Could you try locking the CPU frequency to a single value?

[melomane63]

Set governor on Performance, no luck. camilladsp.log

[HEnquist]

Ok, well it was worth a try. Thanks for testing!

[HEnquist]

Don't have any new clever ideas unfortunately. Does it work better with a 2x or 4x larger chunksize?

[melomane63]

Very quick tested, it seem work with 4096. Not the time now, i test in deep after tomorrow Where is the différence under 32 and 64 bit ?

Ok! There shouldn't be any difference between how this behaves on 32 and 64-bit systems. But the kernel may be somewhat different, not sure how similar these versions are.

[HEnquist]

Does this still happen on the latest release?

[melomane63]

i don't know, i don't use anymore 32 bit version. sorry.

[HEnquist]

Ok no worries. Let's close this issue then.
