[Pkg-alsa-devel] Bug#619402: alsa-base: persistent names for audio adapters.

[peasthope at shaw.ca]

Subject: alsa-base: persistent names for audio adapters.
Package: alsa-base
Version: 1.0.23+dfsg-2
Severity: normal

*** Please type your report below this line ***

Hello ALSA maintainers,

Persistent names are now routinely used for storage devices and for network adapters.  
Contemporary systems can have multiple audio adapters and, of course, a USB audio adapter 
should be hotpluggable.   Therefore I suggest addition of a script /lib/udev/write-sound-rules 
which would create /etc/udev/70-persistent-sound.rules.  This would solve the ambiguity 
and confusion and difficulty with identity of sound hardware.

If this suggestion interests you, I can offer a draft of the write-sound-rules script.

Regards,                      ... Peter E.
