I’ve been using Linux as my main operating system since 2010 and can’t recall having any audio issues. My desktop has 5 sound cards and they all work fine. I don’t use bluethooth for audio, so I guess that makes things easier.

Linux audio issues were common during the transition to PulseAudio, but that was almost 20 years ago now.

Some software for programming an old RadioShack scanner that was last updated in 2003. Since the scanner connects over a serial port, it works perfectly.
