[pulseaudio-discuss] Realtek ALC898 Headphones Issue

[Frederick Zhang]

Hi PulseAudio developers and users,

I'm using a laptop which features a Realtek ALC898 audio card and the 
headphone socket doesn't function very well with PulseAudio.

My laptop has got a GPU switch which can disable either the Intel GPU or 
the Nvidia one at hardware level.

So with the Intel one, the headphone socket works but the audio is 
unbearably loud, even if I turn it down to 5%. With the Nvidia one on 
the other hand, the socket doesn't work at all. However, it can still 
detect headphones plugging in and change the output device for me.

I'm using ArchLinux and here are the possibly related packages I've 
installed:

pulseaudio 10.0-2
intel-tbb 2017_20161128-1
xf86-video-intel 1:2.99.917+760+ge9cd8c21-1
lib32-nvidia-utils 378.13-2
nvidia 378.13-3
nvidia-settings 378.13-1
nvidia-utils 378.13-5
opencl-nvidia 378.13-5

Some of my buddies who're using ALC898 don't get sounds from headphone 
socket, either.

Any clues, guys? I would be glad to provide any further info.
