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-

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]

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)
Subsystem: ASUSTeK Computer Inc. Device [1043:8442]

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.
