Re: port-amd64/56172: Jabra Evolve 20 headset fails to work and may cause panic on removal or audio play

[Andrius V <vezhlys%gmail.com@localhost>]

This issue seems to be fixed in netbsd-current. Jabra headset is
playing sound on audiocfg test. Removing it during test play causes
assertion failure in src/sy/kern_subr_psref.c, line 296 (mismatched
pref target class: 0x0 (ref) != 0xffffede25fb1f7c0 (expected)) though.
