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.
