[alsa-devel] Intel HDA & Realtek issues on ASUS G751JM

[Raymond Yau]

>
> The laptop has 3 jacks. 5.1/4.0 works fine in Windows 8.1 and I'm not
> talking about HDMI/SPDIF.
> If you look at the laptop specification, it says
> 1 x Microphone-in jack
> 2 x Headphone-out jack (SPDIF)
> But the microphone-in jack can also be an output.
> Also, the laptop has two microphones, a pair of speakers and a subwoofer
(?)
> I can also boot Windows and provide information, please let me know
> what you need.
