@youtubemusic I've been using this for months now, I have audio quality set to always high, but it's just terrible. Multiple devices, earphones, headphones, speakers. It's like you've just cut out everything above 15khz. Equaliser settings just distort it and make it more obvious
I'd rather not. The next step is usually to tell me to take some troubleshooting steps I've already taken, and are irrelevant across three different platforms.
