When I installed last December I set up pipewire to use the LFE out for my subwoofer like below:

~/.config/pipewire/pipewire.conf:

Code:
stream.properties = {

channelmix.normalize = true

channelmix.mix-lfe = true

channelmix.upmix = true

channelmix.upmix-method = psd # none, simple

channelmix.lfe-cutoff = 250

channelmix.fc-cutoff = 15000

channelmix.rear-delay = 12.0

}


This has worked fine for 6 months, but yesterday when I turned on my PC it wasn't working anymore.

While troubleshooting, I've set `log.level = 9` (and confirmed that it was set with `pw-metadata -n settings`), but I see no sign of logging to /var/log/messages or anywhere I can think of to look.

It is no doubt due to something I have done, but I haven't touched any sound settings for a long while, and fairly certain that I hadn't even done any updates since last reboot. I've recompiled pipewire.

(Edit: if I plug my cable going to the subwoofer into the speaker output on the PC I get sound on the sub, so I know it's not the cable or the speaker)

Thoughts?

Thanks

Code:
nautilus /home/pvint # emerge --info pipewire

Same issue here. However while trying to figure what I'm doing wrong it somehow started working, during that time I found that the Plasma volume controls are mismatched, LFE is switched with Rear Right.
