In Windows' Device Manager I see an 'Intel SST Audio Device' with PCI ID 0x86:0f28. Indeed, the PCI ID database has this listed as "ValleyView LPE Audio Controller" - http://pci-ids.ucw.cz/read/PC/8086/0f28 . But hda-intel does not have 0f28 as a supported device.
So...what is this 0f28?
It is not an HDA controller. The SST thingy uses I²S codecs.
yes it doesnt look like HDA, but the SoC might have one which can be enabled in BIOS...
I don't think I saw anything like that. The firmware (pleeeeeease, call it 'the firmware', I'm fighting a heroic (quixotic?) but retreating battle against the trend to call a PC's firmware 'the BIOS' even when it's not frickin' BIOS) is pretty barebones, it has 'on/off' switches for various bits of hardware, but nothing more than that, and I'm pretty sure they're all set 'on' OOTB, inc. audio.
Is support for it going to be added?
There is something in sound/soc/mid-x86/, but that is only for the Medfield platform. The PCI SST driver that was not merged four years ago used the ID 080a.
Only Intel knows.
I think Liam or Jarkko might have something for you...
Hope so! Thanks for the reply and the redirect.
Is there any info I can provide to help?
"lspci -vv -d 8086:0f28"?
OK, will get that for you shortly. Thanks for the info.
I'm just about to build a new test image which I'm throwing a couple of kernel patches for other bugs into, I'll grab this lspci output while I'm testing that.
