I have the absolutely same issue on the Pixel 6a. Haven't found a solution, per se, but I've enabled shake to wake so I give it a little nudge in my pocket before I change the song. To avoid accidentally blasting my ears off on full volume, I also disabled volume keys via Poweramp

Just double checked and this is indeed set as default and was when I was using it in the car. I do have the custom volume panel enabled though, if it makes a difference. I doubt that its Poweramp at fault for this specific issue, probably not for the main one either.

Just a quick update. This whole thing might be a pixel problem, rather than a Poweramp one. Recently used it with Android Auto a lot and I noticed on occasion, Poweramp would not start up with the connection being established. Happened with AAudio, OpenSL and Hi-Res. After the Android Auto connection, navigation and everything works as expected, but when opening the "Now playing" feature, it shows Poweramp using the audio channel. Again, have to force stop it and then launch it again just to work at all. Decided to try removing Poweramp to test whether the same thing happens with the built-in music app. Not only does the same thing happen, it somehow bricks the Android Auto connection and I have to cold boot the system in the car. "Now Playing" option shows the same error that the channel is being used, but with no app as the culprit. It is weird to how it happens randomly. I cannot notice a pattern. Will write to the pixel community forums, hopefully Google fixes this.

@maxmp Tried all three modes on my ride to my grandma yesterday and on AAudio there's been no issue with "Now Playing" on the Pixel. Not sure what the issue was with Hi-Res, but I realistically only use it with one bluetooth receiver for my home audio system so its not that big of an issue. I haven't tried it under the Pixel, since I got it recently, but with my previous phone anything else than "Hi-Res" as output produced hissing at quiet parts of any song and distortion at below 50Hz.

I use Hi-Res for all my outputs (Speaker, Bluetooth, USB DAC) I have not observed whether this happens after the USB DAC gets used, will test now. Okay, so it happens when I switch from Bluetooth to USB DAC. It does not happen when I go from USB DAC to Speaker. Seems to me as there is some issue with the bluetooth handoff Further digging in regards to Andre's question - decided to try switching to OpenSL ES. I get no issues no matter the combination of output devices I switch between. It must be something in the latest update that has messed something up with the Hi-Res playback as previously it was working fine to my knowledge.

I have the same issue here. Same build number, android version, but on a Pixel 6a. I noticed this happening whenever I switch from Bluetooth to speaker directly without stopping Poweramp first. If I force stop Poweramp before I turn off my bluetooth, this doesn't happen. If I forbid Poweramp to run in the background, this also doesn't happen. After the error Scott described happens, nothing you do can resolve it, except for restarting your phone. Force stopping Poweramp and the Android intelligence service (which handles the feature) do nothing. Please fix this as soon as possible as I rely on this feature for work partially and I often forget to cut off Poweramp before disabling bluetooth. I'm ready to provide logs and test debug builds if need be.
