Red Hat Bugzilla – Bug 201956
two soundcards in firstboot sound configuration, should have been 1.

Description of problem:
Sound Card Configure found the proper sound card, but also found an
extra sound card not in the system. Only the VIA sound drivers worked
and test sound was fine. So I think sound card detection needs a bit
of work. The extra sound card had a nonsensical name as well, started with a P
and was mostly numbers, maybe one other character, probably 8 chars wide.
Version-Release number of selected component (if applicable):
fc6 test 2 DVD iso version
Only installed once, so haven't tried to reproduce this problem.
Steps to Reproduce:
2 sound cards found
Just VIA sound card to be found in my box.
System AMD 64 bit Athlon 2400
200 GB SATA hard drive
512 MB Ram Memory
USB - printer HP PSC 1210
6600 GT Nvidia Video Card ( I don't often install NVIDIA's drivers,
if I'm not doing something that needs the extra performance. )
17" Samsung monitor synmaster 750s
On board VIA sound

It's the mpu401 device, It isn't a bug.
Thanks for the information. Is the mpu401 device just a subfunction
of the VIA card for sound input from keyboards? I used to think it was, but I
know little about sound cards, and MIDI, I just want some basic sound to play,
which the sound card configuration gets working fine (thanks).
But if the MPU is just a function of the VIA built in soundcard, I would suggest
having its MPU be configured on the VIA tab. If other OSes configure the two as
seperate devices though, then I Fedora should follow the defacto standard in the
area, and keep them as seperate sound cards.
I'm not sure whether I can change it, s-c-soundcard just uses informations which
come from kernel. The MPU-401 is a generic MIDI I/O interface for PC and can be
used for sound input from keyboards, so this may be your case.
