JFTR, we've seen users that report distorted sound on their macbooks
when using jackd.

The workaround is to force 16-bit output:


Chip in question was the Cirrus Logic CS4206. We don't know yet which of
the formats (32/24) is broken, maybe only one, maybe both.

I happen to have a spare MacBookPro around, but I won't have time to
look into that myself anytime soon.

If somebody else has such a device and wants to give it a whirl, feel
free to go ahead. ;)
