I have the following notebook: Acer Predator Helios 500 (intel cpu/nvidia gpu), with the folllowing:
CPU: Intel i9-8950HK
GPU: NVIDIA GTX 1070 Mobile
The problem I’m having is that I don’t have any sound output from the internal sound card. It works as intended on Windows 10, detecting both Headphone (line-out) jack and internal speakers.
In Linux, I have no sound, both internal speakers or headphone (line-out).
I have the following detected:
lspci -nn | grep -i audio
00:1f.3 Audio device : Intel Corporation Cannon Lake PCH cAVS [8086:a348] (rev 10)
lspci -v | grep -A7 -i “audio”
00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10) (prog-if 80)
Subsystem: Acer Incorporated [ALI] Cannon Lake PCH cAVS
Flags: bus master, fast devsel, latency 32, IRQ 152
Memory at 404a100000 (64-bit, non-prefetchable) [size=16K]
Memory at 404a000000 (64-bit, non-prefetchable) [size=1M]
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel
It is based on ALC299, if I’m not mistaken.
Can anyone help me solve this problem?
