Some mother boards use bus 0 for PCI addon cards thus causing multiple "Internal Audio" cards.

(For reference, I don't have this h/w: the report is really from user qsp on IRC on 19th November)

This was reported before but I can't remember if this was on IRC, the ML or elsewhere... I think it was IRC so creating this bug to track it. Apologies if it's a dupe.

It seems that some motherboards use bus 0 even for add on PCI cards. We currently use bus 0 to hint to us that the card is built into the mobo and thus name it "Internal Audio" to save confusing the user with complex chipset names etc.

This seems to break on some setups. I'll attach some files from an affected user.

This might have happened to me when I booted from a Live USB of Kubuntu Meerkat 10.10 post-RC-nearly final release. I have a VIA K8V deluxe motherboard with built-in internal VIA 8237 chip, and a Creative Audigy (Platinum?) ZS PCI card. PulseAudio 0.9.21-63-gd3efa-dirty gave both the same device.description string "Internal Audio Analog Stereo" and muted the former, so I filed bug #863 and coling suggested it might arise from this bug. pacmd list-sinks gave them device.product_names of "VT8233/A/8235/8237 AC97 Audio Controller" and Creative Labs "SB Audigy", and sink names of

        name: <alsa_output.pci-0000_00_0d.0.analog-stereo>   <-- my Audigy ZS
        name: <alsa_output.pci-0000_00_11.5.analog-stereo>   <-- my VIA 8237

I will attach lspci -vvv output, though I'm now back to Kubuntu Lynx 10.04.
