Comment 61 for bug 580183

I have been having a look at the output of lspci. It turns out the different cards can be differentiated. These are my results:
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
        Subsystem: ASUSTeK Computer Inc. Device 8437
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
        Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
        Latency: 0, Cache Line Size: 32 bytes
        Interrupt: pin A routed to IRQ 46
        Region 0: Memory at f7cf8000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

The lspci attached to this bug report is thusly:
00:1b.0 Audio device [0403]: Intel Corporation N10/ICH 7 Family High Definition Audio Controller [8086:27d8] (rev 02)

The important line seems to be the subsystem. I've asked our vendor to contact Asus about possibly getting some information on the model I've got. Can I get some more results from "lspci -v" pertaining to the audio device from those having issues?

This should enable us to get an idea of how many different revisions there appear to be for this sound card and hopefully means we'll be able to fix a range of them.
