Kudzu sees the usb microphone in my logitech quickcam pro 3000 and prompts about 4 times about an 'unknown' soundcard. If I look in /etc/sysconfig/hwconf it has the 'unknown' device several times. Everytime I reboot kudzu asks me about it. I can bring this in sometime this week if you'd like to look at it.
It *probably* has four separate USB audio devices in /proc/bus/usb/devices - what does that look like?
Yes, it does have four 'audio' devices. Currently it's working-as-designed. May need to come up with a better design. :)

Created attachment 101872 [details] kudzu-ignore-lots-speakers.patch Ignore all the usb devices when the "Alt" (alternate) is > 0.
I made this patch following a conversation with Thomas Sailer, the maintainer of the USB audio stack: > It shows 7 audio devices being added. Which is consistent with the > output from /proc/bus/usb/devices[1]. Well, no, there's one device in your devices file whose interface 1 has 7 altsettings, i.e. alternative and mutually exclusive ways to operate the device. > I was wondering what are all those audio devices used for, and if it was > safe for kudzu to "collapse" them all into one. I don't know why kudzu reports each altsetting separately, sounds like a kudzu bug to me... It doesn't quite fix the problem, though: T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 4 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0471 ProdID=0101 Rev= 1.00 S: Manufacturer=Philips Electronics S: Product=Philips USB Digital Speaker System C:* #Ifs= 3 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 0 Cls=01(audio) Sub=01 Prot=00 Driver=audio I: If#= 1 Alt= 0 #EPs= 0 Cls=01(audio) Sub=02 Prot=00 Driver=audio I: If#= 1 Alt= 1 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 56 Ivl=1ms I: If#= 1 Alt= 2 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 112 Ivl=1ms I: If#= 1 Alt= 3 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 112 Ivl=1ms I: If#= 1 Alt= 4 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 224 Ivl=1ms I: If#= 1 Alt= 5 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 168 Ivl=1ms I: If#= 1 Alt= 6 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=audio E: Ad=04(O) Atr=09(Isoc) MxPS= 336 Ivl=1ms I: If#= 2 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid E: Ad=83(I) Atr=03(Int.)

Added, will be in 1.1.73-1.

Please note, that the microphone on the USB webcam is loaded as the FIRST sound card. Thus many people complain that they loose sound when they boot with their webcam connected! This shouldn't happen, if the system has more than one sound devices, the user should be asked which one will be used primary. The same problem happens when multiple sound cards are installed. In order to fix the problem with the USB webcam microphone, this has to be added in the modprobe.conf: alias snd-card-0 <your-sound-module> options <your-sound-module> index=0 alias snd-card-1 snd-usb-audio options snd-usb-audio index=1 this will make the usb microphone come second, thus not affect the overall sound output of the system. btw, we've been reporting this bug since RH8 and RH9, its about time it gets fixed ;)
