Hello
(and sorry for previous post as an answer and not new thread...)
I'm using Ques OS since 4 months and have an audio issue in DOM0 since last
Wednesday (04/08/2020), and I'm unable to fix it...
Any help or advise will be welcome !
Issue Explanation:
Intel PCH Audio card 0 is no more present in pulseaudio GUI, only the
NVIDIA HDMI audio card 1 is present.
Although hardware is OK (verified with my previous debian hard drive today).
Commands, configuration and things that may help:
Kernel version: 4.14 (latest versions cause issue on laptop screen
power off/on with Nvidia card...)
Qubes release 4.0-8
* lspici : OK*
00:1b.0 Audio device: Intel Corporation 8 Series/C220
Series Chipset High Definition Audio Controller (rev 04)
Subsystem: Hewlett-Packard Company ZBook 15
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at d0330000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: pciback

ignored)
