I have no sound via the speakers in the laptop or the headphone jack. Microphone works fine as does sound via HDMI.
The Realtek codec is ACL 1220 - which I read it is only supported in kernel 4.11 or later.
I have tried:
- Use OSS4
- Use Kernel 4.9, 4.10, 4.11, 4.12, 4.13 (multiple versions of each)
- Updated firmware in Mint to 1.164.1
- Several modifications of alsa-base.conf
- Used the daily source for alsa
Strange part is Mint thinks there speakers and headphones are working fine, signals for sound are being sent and volume control works fine - no "Dummy Output" or anything like that.
I even put Windows on to check that the sound card itself wasn't damaged.
Output of aplay -l (4.8 kernel)
Code: Select all
aplay -l
