bytcr-rt5640 sound only on the right side

[pinpox]

Hello,

I have copied the UCM/bytcr-rt5640/ files as desrcribed and blacklisted the hdmi audio module since it was making problems.

I have now sound, but only on the right speaker. If I plug the headphones in I can hear sound on both earpieces after changing the output device in pavucontrol.

I have a ton of controls in alsamixer and have tried to find something related but no luck.

One minor issue that might be connected: After switching audio outputs in pavucontrol I have no sound at all. I have to go into the Configuration tab and select the "Off" audio profile, then select "Hifi" again. After that I have sound on either the headphones or the (right) speaker.

What is the issue here? I'm glad to provide any information you need to debug this.
