Audio Hardware Setup will not stick with Analogue Stereo Duplex but always reverts to HDMI profile even after clicking apply. I’m trying to get Mixxx working with analogue headphone output & think this may be a bug with SUSE. Mixxx says analogue channel is unavailable. Sound works like it should with regular use, analogue output from left/right speakers & muted when headphones auto detected. I have set analogue output as master channel in preference over HDMI. Mixxx supposedly works it’s own magic by outputting to two separate channels (or sound cards?); Headphones and speakers at the same time.
