Bug#841750: XPS13 Jessie->Stretch: No sound

Package: upgrade-reports
Severity: important


Hi folks,

recently, I felt the need to upgrade my XPS 13 laptop (2013 model?) from
Jessie to Stretch, but have not had any sound ever since.

To be more precise, I had no sound ever after trying the 4.7 backported
kernel on Jessie, which was what originally prompted me to upgrade to
Stretch.

The device seems to be there:

# lspci -v
...

00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
    Subsystem: Dell 7 Series/C210 Series Chipset Family High Definition Audio Controller
    Flags: bus master, fast devsel, latency 0, IRQ 28
    Memory at d0510000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: [50] Power Management version 2
    Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
    Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
    Capabilities: [100] Virtual Channel
    Capabilities: [130] Root Complex Link
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel


But Pulseaudio does not find it. I already deleted ~/.config/pulse, but
to no effect. pavucontrol shows only "Digital Stereo" and two "Digital
Surround", but all being "unplugged".

Heeding the advice to look into the BIOS, I found no settings relating
to sound, and that my BIOS is A09, which is well above the recommended
A02.

I installed firmware-linux-nonfree and firmware-intel-sound, but to no
avail.


Cheers,
Toni
