I recently bought a Dell Venue 8 Pro - a Bay Trail / Valley View-based Intel tablet - to try and get Fedora running on it. Among the many things I'm currently fighting :) , the sound doesn't work. snd-hda-intel is not loaded at all, and there are no audio devices present at any level. 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. The commit for 'Bay Trail' audio support added the ID 0f04: https://lkml.org/lkml/2013/5/16/38 So...what is this 0f28? Is support for it going to be added? Is there any info I can provide to help? (I can boot Linux on the tablet and get info out of it _just barely_, but it's pretty painful - there's no wifi and an install to 'disk' (really a usb stick) doesn't work too well, so I'm stuck working in a live image with no network). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net ^ permalink raw reply [flat|nested] 14+ messages in thread

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.

So I got time today to poke at this device again, and here's something: it's not actually a PCI device at all, I missed that. Neither lspci (Linux) nor pcitree (Windows) shows a PCI device with ID 8086:0f28. It must be connected some other way, SDIO or something. So, I don't know how to get more info on it, really.

It must be a device controlled by i2c/spi/whatever, not a standard HD-audio. IIRC, the control can be taken from ACPI, but it's not implemented properly yet.

Heh, that's actually just a mirror of the git ASoC branch. All those patches went through this very list last week. I don't know precisely how the upstreaming process goes for this stuff, but I'm guessing it'll wind up in 3.14 or 3.15.

FWIW, I tried building a 3.14rc3 kernel with these patches applied and the drivers enabled as modules. On boot on a Dell Venue 8 Pro, all the relevant modules are loaded, but there's no ALSA device, and no obviously useful errors in any logs, or useful output from alsa-info.sh. Is it expected that the driver doesn't actually work yet? Per the recent commits, do I need some kind of firmware? Any debugging that would be useful?

The current patches upstream are for the low level parts of the Intel DSP drivers. Jarkko and I still have to upstream the upper layers of the drivers (probably today) and you will also need firmware. Once upstream the drivers will support Valley View, Baytrail, Haswell and Broadwell. The firmware for Baytrail and Valleyview will be available shortly too.

Please let us know when the firmware is available. I have few question here, the i2s mode should be enabled in the platform drivers right. In the Bayley Bay bios I saw that the LPE audio could be enumerated via PCI or ACPI, the patches I saw mostly cover the ACPI mode. Will the PCI mode be covered in the patches.
