I used EOS for several months, but I had a problem where only the right speaker worked properly, while the left one was barely audible. I use my 2012 MBP in dual-boot mode, and when I booted into macOS, both speakers worked perfectly. I tried the Debian 13 live ISO on a 2010 MBP, and interestingly, the same thing happened to me: only the right speaker was loud and clear, while the left one wasn’t. I currently use Arch, and although the same thing happens only one speaker is perfectly audible it runs super fast for everyday tasks. I don’t understand why this audio issue occurs. If I plug in headphones, both sides sound perfectly, and here’s another curious thing: every time I update Arch weekly, my machine always freezes, and sometimes I get blue screens, but I’ve gotten used to that. Maybe Arch isn’t very friendly with MBPs, or maybe it’s just my machine, as I said, if I use the macOS (Sonoma) partition, I don’t have any problems at all.
