Pipewire - Incorrect mapping to 5.1 channels
Hey all,
Running a Fedora 34 Workstation (kernel 5.14.9) install here, with a Creative SoundBlaster AE-7 hooked up to my stereo headphones, using digital surround for 5.1 (I'll note here that the system sees the device as an analog 5.1 output, which is correct as the 5.1 HRTF digital mix is done by the soundcard)
I've known that surround support has been weird since I switched to Linux from Windows, but I've figured out that it seems like the surround channels are incorrectly mapped by default on my device.
They are mapped as following, according to the Gnome audio settings:
CHANNEL NAME (Gnome Settings) | SURROUND POSITION |
---|---|
Front Left | Rear Left |
Front Center | Front Left |
Front Right | Rear Right |
Rear Left | Front Center |
Rear Right | LFE |
LFE | Front Right |
