Hello there,

I have Ubuntu 16.04LTS installed on the Clevo P751DM2-G, also marketed as the Schenker XMG U507, the System76's Serval WS (2017 model), the Eurocom Sky X4E2, among others.

The sound card is the Realtek ALC898 with the following output configuration:

1. One SPDIF/headphone combo jack (to the right) 2. One Line Out. 3. One Line-In. 4. One Mic-In.

Background information:

On Windows, one can use the Realtek HD Audio control panel pop-up menu on jack detection to set the output type when an audio device is plugged in to an appropriate jack, combined with Sound Blaster X-Fi MB5 software to enable post-processing effects such as Bass, noise cancellation, etc.

What I have tried so far:

1. Setting the model definition at /etc/modprobe.d/sound.conf with the following entries:

options snd-hda-intel model=no-primary-hp enable=1 index=0

Using such a line worked before on an MSI GS43VR 6RE Phantom Pro that also has the same (or a similar) ESS Sabre Audio DAC component.

Expected behavior:

When plugged into the microphone jack, the ESS Sabre DAC should be activated and sound should be routed to the headset.

Observed anomaly:

Sound comes out through the speakers instead.

However, the line-out output works. In that case, when plugged into the line out, Audio works as expected.

I was able to report this as a bug to Launchpad, with the information below:
