Audio seems rather buggy on #FreeBSD 16-CURRENT today. Sometimes, audio simply doesn't play, even though it's playing. Dunno how that's supposed to make sense.
framework 16 still?

long shot, but i had spotty audio (including sometimes not being detected at all) and a funny left channel.

the connector for the speakers isn't a plug as much as it's a delicate snap. reseating this fixed my issues.

i probably, at some point, tossed my bag down and it came loose.
@jason In this case, it's all my laptops, both Dell and Framework. So I don't think it's a hardware issue. The issues started appearing only after the recent-ish sound work in the FreeBSD kernel.
