I noticed a problem with the sound on my device after using Poweramp's Hi-Res audio output. After leaving the app, when I tried to play audio through any other channel (i.e. every other app except Poweramp while it is using Hi-Res mode) I would only get a high pitched chittering sound.
This bug affects all audio outputs on the device that use the internal DAC and is extremely annoying so it would be nice to have a fix ASAP.
I'm using a Samsung Galaxy S7 with the Exynos chipset and the Lucky CS47L91 DAC. I have the latest updates applied and this has happened multiple times.
