Public bug reported:
Binary package hint: phonon
I'm running Maverick 10.10, Phonon Configuration Module version 4.5.1,
default Phonon Xine backend 0.2.60, and default PulseAudio. I have a
Creative SB Audigy ZS card and built-in motherboard VIA 8237 audio.
When I bring up System Settings > Multimedia > Phonon > Device
Preference, it lists "Internal Audio Analog Stereo" twice, as does panel
> KMix > Select Master Channel. This is insufficient info to
distinguish my audio devices.
KDE has to provide more information so I can tell the two devices apart.
There's plenty of additional detail available to disintinguish these at every
layer of the audio stack, PulseAudio, Alsa, and PCI. For example, `pacmd
list-sinks` presents in part:
* index: 0
name: <alsa_output.pci-0000_00_0d.0.analog-stereo>
properties:
alsa.card_name = "SB Audigy 2 ZS [SB0350]"
alsa.long_card_name = "SB Audigy 2 ZS [SB0350] (rev.4, serial:0x20021102)
at 0xb400, irq 18"
device.description = "Internal Audio Analog Stereo"
* index: 1
name: <alsa_output.pci-0000_00_11.5.analog-stereo>
properties
alsa.card_name = "VIA 8237"
alsa.long_card_name = "VIA 8237 with AD1980 at 0x1000, irq 22"
device.description = "Internal Audio Analog Stereo"
Any of this stuff in addition to device.description would distinguish
the two audio devices.
Either KDE could notice it's presenting two identical device names and append
additional info, thus
Internal Audio Analog Stereo (SB Audigy 2 ZS [SB0350])
Internal Audio Analog Stereo (VIA 8237)
or it could have a tooltip or properties that provides the extra info.
I say "KDE" here, but I have assigned the bug to Phonon. I think the
System Settings code is in phonon_devicepreference_update in package
kdebase_runtime, I'm not sure where the KMix Select Master Channel code
lives.
It may be a PulseAudio or PCI glitch that I have two sound devices with
the same name, I filed bug http://www.pulseaudio.org/ticket/863

Phonon does not provide enough info to identify devices
