Bug ID: 88941
Summary: [OS X] (USB) sink/source names are meaningless and
vary across pulseaudio restarts
Product: PulseAudio
Version: unspecified
Hardware: Other
OS: Mac OS X (All)
Status: NEW
Severity: major
Priority: medium

pacmd list-sinks > pacmd-list-sinks-1.log
On OS X, pulseaudio attributes human-unreadable names to the sinks and sources
it detects, and in addition to that, they vary across restarts for USB sound
devices. They may also vary for other external sound devices (FireWire), but I
don't have any way to test that.
The attachments highlight the issue: they are the output of `pacmd list-sinks`
for 2 consecutive runs of `pulseaudio -C`:
> pulseaudio -C
> pacmd list-sinks > pacmd-list-sinks-1.log
> pulseaudio -C
> pacmd list-sinks > pacmd-list-sinks-2.log
> pacmd list-sources > pacmd-list-sources-2.log
> pulseaudio -C
> pacmd list-sinks > pacmd-list-sinks-3.log
> pacmd list-sources > pacmd-list-sources-3.log
The implications are clear: it's impossible to set a default sink and/or source
persistently, other than to the internal devices.
