[alsa-devel] Headset doesn't work for HP EliteBook 755 G2
Hi, first time here, following suggestion [1] to report non-working default configuration, which I found how to make work.
I checked using the latest stable kernel 4.4.2 and my headset jack doesn't work by default but my fix does work, on Scientific Linux 7.2 using the 4.4.2 kernel from the ELRepo repository. I also checked using Ubuntu 16.04 alpha with its 4.4.0 kernel and the problem and fix are the same.
My laptop is an HP EliteBook 755 G2 from mid 2015 [2] that has a combined headset (headphone + mic) jack that doesn't work by default. The speakers work fine by default and they mute when a headset is plugged in, but the headphones don't work.
The snd-hda-intel module handles my device. The codec is Realtek ALC3228. I have the latest BIOS update from HP.
I got it working by passing model=hp,headset-mic to snd-hda-intel. I found this fix in an alsa-user message about a different HP laptop with the same codec [3], but I had to modify the message's fix by only including the module option for model= and omitting the other options and aliases that seem to be specific to Arch Linux. I tried using only "hp" or only "headset-mic" as the value for model= but neither worked.
Attached are my outputs of alsa-info.sh from before and after I did model=hp,headset-mic.
Also, there's another problem after enabling model=hp,headset-mic, which I found how to fix: There is a very annoying squeaky background noise in the headphones that's independent of adjusting the volume level but it does stop when the headphones are muted. I tried a different headset and it's the same. I found how to suppress this by using the white_noise_fix.py script from [4] as described at [5,6], which apparently does some ioctl verbs to adjust the amp gain. I thought this might be something that should be fixed/adjusted in the kernel module(s) that handle this device, so that the white_noise_fix.py isn't needed. If so, maybe it's worth mentioning that when my laptop resumes from sleep, the background noise comes back, so I have to run white_noise_fix.py again.
I'm willing to help investigate my hardware more or try other configurations or distros if requested. If it's worth mentioning, I found someone else with the same laptop who has the same non-working headset problem, see [7].
I'd like to help get this fixed in Ubuntu 16.04 before its release. If the proper fix is in the kernel ALSA, I'm willing to go through Ubuntu's process for asking them to incorporate it in 16.04.
Apologies if I've misdirected this report.
Thanks for your work on ALSA! -- Derick

The point is the comma. Your Realtek codec is assigned as the secondary, and model option takes multiple values, one for each slot. So, you'd need to pass "model=,headset-mic"

Thanks, I'll compare them. Isn't the any functionality lost by this option? Everything (except for the noise issue) works by that?

Such a noise often comes from the analog-loopback. Try to turn off "Loopback Mixing" mixer switch.

Passing only "model=,headset-mic" does work fine. I tested: internal speakers, internal mic, headset headphones, and headset mic, and they all work (after some mixer adjusting). (I haven't ever tried the first-slot HDMI/DP audio device but will try to some time.)
Also, there's another problem after enabling model=hp,headset-mic, which I found how to fix: There is a very annoying squeaky background noise in the headphones that's independent of adjusting the volume level but it does stop when the headphones are muted.

Disabling "Loopback Mixing" does stop the noise. (Be careful when toggling this with headphones on, loud pop noises can happen with my device.) The white_noise_fix.py script wasn't needed.
Attached is my latest alsa-info.sh output from when it's all working with the above applied (and with other mixer settings that make everything usable for me).
Thanks! -- Derick

Thanks. FWIW, below is the fix patch doing both (setting the quirk and disabling loopback). I'll queue this up.

-- 8< -- From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Fix headset support and noise on HP EliteBook 755 G2
HP EliteBook 755 G2 with ALC3228 (ALC280) codec [103c:221c] requires the known fixup (ALC269_FIXUP_HEADSET_MIC) for making the headset mic working. Also, it suffers from the loopback noise problem, so we should disable aamix path as well.
