Description dovla091 2019-10-08 07:31:47 UTC 
Created attachment 1623428 [details]
Latest dmesg

Description of problem:
Internal microphone is not recognized, and possibly front speakers (as I don't hear the sound)


Version-Release number of selected component (if applicable):
Kernel release: 5.4.0-0.rc2.git0.1.fc32.x86_64
Driver version: k5.4.0-0.rc2.git0.1.fc32.x86_64
Utilities version:  1.1.9

tested with previous kernels as well starting from 5.0.x, 5.1.x, 5.2.x and 5.3.1. Even rawhide is not supporting Realtek ALC285 

alsa-info script included in the attachment

How reproducible:
Use any HP Spectre X360 (2018) 13" model ap03xxng
load Fedora 30 or 31, and check for Microphone in the settings.
Also it appears that not all speakers are working, but only 2 out of 4


Actual results:
After testing on Fedora 30, 31 with kernels which I wrote above, the microphone detection is missing. Also sound to all 4 speakers are not recognized.


Expected results:
Microphone should be supported, and speakers as well

module: Realtek ALC285


Additional info:

In the attachment you might find alsa-info script output, and dmesg from my PC.

Comment 4 dovla091 2019-10-08 18:03:09 UTC 
There were some attempts to patch this issue in regards to internal microphone and all 4 speakers.

While investigating this issue, I found this sit with the same issue. It appears that someone created a patch.


So, the patch for this is made and available here: https://github.com/gled-rs/linux-hp_ap0xxx

Since I don't have a hw programming knowledge, perhaps someone can look at this patch, review it and if it is good/valid, to implement it in the new version.

Comment 6 Tim Jackson 2019-10-09 20:12:49 UTC 
This bug is filed against the alsa-firmware package but doesn't sound like a
problem with alsa-firmware.
alsa-firmware contains firmware drivers for a very small number of specialist 
sound cards only.

Please be aware that problems with sound can be caused by many different
software components within a Fedora system (including ALSA kernel modules,
PulseAudio, desktop volume controls, individual applications and more) and
you may find it easier to get some informal help to track down the problem 
before filing bugs (if necessary), so that you can file them against the 
right component and the appropriate person can help.

Information about debugging sound problems can be found here:

Comment 7 dovla091 2019-10-10 06:36:18 UTC 
ok, so what about microphone which is not listed? Again, the bug was filed primarily for microphone which is not recognized.
Comment 8 Jaroslav Kysela 2019-10-10 08:27:43 UTC 
It's Intel's Cannonlake platform. Most likely, the digital microphone (DMIC) is connected directly to the DSP. You need sof-pci-dev driver and appropriate firmware. Unfortunately, not all pieces are ready for the distributions (firmware, UCM configs, the kernel auto-detection for such hardware). We are working on it with Intel. Please, wait for few weeks.
Comment 9 dovla091 2019-10-10 08:56:09 UTC 
Hi Jaroslav.
Thanks for the explanation. I am only a sys engineer, so in regards to hardware and programming part, I rather chose to report and leave it to the experts in that field.
Once again thank for response and looking forward for your patch to be released.

Brgds.
Comment 10 dovla091 2019-10-25 19:17:51 UTC 
Hi again, 
any progress on this issue? Is there any kernel mailing list where I can keep a track on the progress instead of bugging you and writing a message on bugzilla?

warmest regards
Comment 11 Jaroslav Kysela 2019-10-31 18:15:16 UTC 
Unfortunately, this issue hits the kernel, firmware and the user space packages. I have an update for you: The functional SOF driver will be in the kernel 5.5 (requires to add SOF firmware files version 1.3.0) and the working configuration will be in the alsa-ucm package version 1.1.10. So we need to push all those bits to Fedora when released.
Comment 12 dovla091 2019-10-31 18:25:30 UTC 
Hi again. Thnx for keeping me in a loop.
And many thanks for taking a huge effort for fixing things and making our hardware useful.

Best regards.
Comment 13 Jaroslav Kysela 2019-11-19 08:41:44 UTC 
Okay, things are finally moving. I will continue in bug#1772498 and closing this as a duplicate. Please, test the kernel + user space.
