Intel Sunrise Point-H HD Audio issue

[Alexvar]

Hello there!

Around 3 months ago, I installed LM on my laptop. Everything worked fine, but the audio doesn't work. To make a long story short, I started a thread in this section, and with the help of user MrEen, among others, we tried to solve the problem, but at the end we couldn't, so I decided to wait till LM 19 came out, then I installed it, but the audio still doesn't work.
I'm starting this new thread to see if I can get help from more people, so if you have any ideas, please tell here! Any help will be hugely appreciated.
you can go to the older thread following this link: viewtopic.php?f=48&t=267963

Some things to consider:

1) My laptop is an HP Pavilion 15-bc008ns, which has, of course, an Intel Sunrise Point-H HD Audio chip.
2) I have tried several Ubuntu-based OSes (Ubuntu, Kubuntu, Ubuntu Mate...), and I have had the same issue, so I don't think this is a LM-exclusive issue
3) I'm currently running LM 19 Cinnamon 64-bit off a USB Drive, so I don't have to overwrite the hard disk for now. I have installed Windows 10 on the hard drive for the sake of compatibility
4) I'm currently running Linux Kernel 4.15.0-23 (Though I just have received the 4.15.0-24.26 update, which I'll install after I post this thread)
5) Here's some terminal outputs for you:

Hi again Alexvar!

I've been racking my brain for a while on this and finally realized we never used some built in linux troubleshooting tools. This is new to me as I've never had any real issues with my system since I made the switch last year, but lets see if we can get some useful info from dmesg | grep -i sound and dmesg | grep -i audio and hopefully that'll help track down the cause.

[Alexvar]

Hello!
I tried both commands:

dmesg | grep -i sound doesn't give any output
dmesg | grep -i audio gives the following output:

Code: Select all

[   10.141846] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])
[   15.180946] hdaudio hdaudioC0D0: cannot read sub nodes for FG 0x10

Which is, I think, the same error message I discovered back then, so back to the starting point...
While I wait for an answer, I'm going to check to see if I missed any of the solutions from the older thread

[MrEen]

Oops, I missed one: dmesg | grep -i snd

[MrEen]

Okay. I'm going WAY out on a limb here. When I googled your error about sub nodes I could only find it in one place here (on line 401.) Moving up one level to this page I see that hdac_device.c is described as "Copying sync power state helper to core"

I rather doubt this is going to help, but try this in the terminal: xed admin:///etc/modprobe.d/alsa-base.conf (This may ask for your password twice.)I'm not on 19 so haven't tested this method for opening system files for editing. Once the file is open, scroll to the bottom and add options snd-hda-intel power_save=0 then save the file.

Reboot and cross your fingers and test sound. (If it didn't help, undo that change.)

If nothing else, what I found may at least help somebody that knows this stuff get you fixed.

[Alexvar]

Hello!

Well, I tried dmesg | grep -i snd and it actually gave me a few error messages!

This must be the core of the problem!

There is also another output, but I don't think it's relevant. Just seems to be a list of loaded stuff

I also tried changing the alsa-base.conf file, but that didn't work.

[MrEen]

I can't remember if we tried this. Can you disable the audio codec in your BIOS? If so, try that, then re-enable it on the next boot.

See this thread for a very similar problem to yours that was solved with this method. Temüjin over there is really great with sound problems. I tried to see if (s)he was a member here as well but I didn't want to go through 123 pages of usernames starting with "t" to find out, and using the advanced search function looking for "sound" or "audio" with author "tem*" didn't find him/her.

[Alexvar]

Hello!

My laptop BIOS doesn't have an option to enable/disable the audio codec, or at least that option is not visible. In fact, 70% of the BIOS configurations are locked and can't be modified (Dang! can't we just do whatever we want with our PC's?)

Anyway, I guess I'll send a PM to Temüjin to see if he can give me a hand

I really want to thank you for all your support and dedication to my problem! You are awesome!!


BTW I was wondering… Is there going to be a release of the ALSA driver package for Bionic (the version LM 19 is based on)?

[MrEen]

You are very welcome. I'm truly sorry we couldn't get this resolved.

Regarding the ALSA driver update, I've been watching for that myself. I did learn (via a post by Temüjin) that the Aardvark version works for kernel 4.13. I'm hoping Bionic shows up soon.

Best of luck to you!

[MrEen]

Hi Alexvar.

Your plight has bothered me for a while so I did some rather intensive searching recently and found a few things worth trying.

First we should get some info before altering anything just to have a record of it and it may come in handy later.

Code: Select all

sudo lspci -vvs 00:1f.3

Code: Select all

lsmod | grep snd

Now let's make another change to /etc/modprobe.d/alsa-base.conf (xed admin:///etc/modprobe.d/alsa-base.conf) by first making sure we've removed any old manual entries such as model= or power_save= at the bottom of the file. The first thing I'd like you to try here is options snd-hda-intel model=ref followed by a reboot then sound test. Even if it's not working, check if any cards were detected with cat /proc/asound/cards before moving on to the next step.

If still not working, and no cards detected, simply change that line to options snd-hda-intel probe_mask=8 and reboot and test again. Again, check for cards. I'm really hoping this one is going to get us somewhere closer to solving this.

If none of this helped at all, show me the results from the lspci and lsmod commands from above along with dmesg | grep -i snd again.

Damn, I missed the part about Windows 10 at the start of this thread. I am assuming sound works fine there. If so, boot into Windows and find out what audio codec it's using (such as Realtek ALC226.) Might be under something akin to Control Panel > Sound then we might find a better option for alsa-base.conf.

Also, it appears there was a BIOS update last month (though just for security enhancements I think.) I don't know if that update removed any previous updates from the list that may have helped. Might be worth a shot while over in the Windows OS.

When leaving Windows to come back to Mint do a complete shutdown first after making sure fast startup is off (Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Click Turn on fast startup (recommended) so that the checkmark disappears then click on Save changes.) You'll probably have to repeat turning that off after most/all updates in Windows.

Again, good luck!
