sound card (chtmax98090)

That is what I am dealing with in my HP 14 Chromebook.
Correction, it is now my Hp 14 Puppy laptop! Very Happy Very Happy

You do seem to be trying some things I have not.

Got any ideas on getting a working Pulseaudio pet package that will install into Bionicpup64 8.0?
I have tried several found around the forum, but still get dependency stuff needed. I am finding out why people hate Pulseaudio for Puppy Linux.
That thing wants everything and the kitchen sink. Rolling Eyes

bigpup, I'm going to try to exhaust alsa attempts first. The biggest problem for me is, I really don't yet understand all that goes on to make audio happen in general. What is required re. initialization of hardware and when, what kernel modules are needed, and when, what needs to be blacklisted, what does ALSA need in terms of configurations, and how does it work.

I'm just hacking now, not understanding what the whole audio process looks like.

Things I've picked up in readings along the way, though:

1.) There is a problem with the way this chip was implemented. Some conflict of timing and interrupt assignment during initialization and some whacky Google code facilitating. I read references to this somewhere in the development specifically of GalliumOS. Trying to find that reference again.....

2.) And, a needed alsamixer setup to enable sound (I believe that is the GaOS /usr/share/ucm files that I mentioned last post).

3.) And possibly some bootcode re. acpii needed.

re. 1.) above: maybe the pci audio card assignments 1 and 2 for GaOS vs. 0 and 1 for BPup64 is a significant difference after all, if it relates to the timing of the initialization of those cards. And if card initialization timing is the key to the problem.

This morning I'm going to try to find that timing problem reference...

I wonder if something is needed in /usr/share/alsa/ucm

There is stuff here that is for it:

Edited (sound works):

Here is the present setup method on Bionicpup64 (with ozsouth's 5.4.27-64oz kernel) specifically for an Acer R11:

1.) Install firmware-intel-sound deb:
https://packages.debian.org/sid/firmware-intel-sound

2.) Need to create usr/share/alsa/ucm/chtmax98090 with two files: https://github.com/GalliumOS/galliumos-braswell/tree/master/usr/share/alsa/ucm/chtmax98090

3.) Download https://github.com/GalliumOS/galliumos-distro/files/1235825/asound.state.txt

4.) Open console in the download folder and execute:

Code:
alsactl -f ./asound.state.txt restore 0


(My chtmax98090 is device 0 in the code above. If yours is different , change the number after "restore")

You may have to reboot after all of the above to get sound working. I used the Multiple Sound Card Wizard to select card 0 Device 0. (Card 0 Device 1 "Deep Buffer Audio" doesn't yet seem to work, but actually they are the same, anyway.)

Correction:
Should be /usr/share/alsa/ucm/chtmax98090

For this step, I got the stuff from here as a package.
https://github.com/plbossart/UCM
When unpacked, it had the chtmax9890 directory with needed files in it.
Copied the chtmax98090 directory to /usr/share/alsa/ucm

Now, I wonder how you would do this for other sound hardware, in other Chromebooks? Idea

Slight sound problem.

On reboot had to enter
Code:
alsactl -f ./asound.state.txt restore 0

To get sound working.

I kind of have a Bionicpup64 8.0 frugal install with a lot of hacking in it.

I think I need to do this all with a clean fresh frugal install.
I will report back my results.

Thanks bigpup.
I don't have to repeat the alsactl-assound fix on mine when rebooting. It stays.

Just tested the microphone, and it works, too.

I haven't tested yet, but there might be a problem (as mentioned at GalliumOS) of the headphone jack not registering when you plug/unplug. Maybe not. Seems minor by comparison with what was just gained on these Chromebooks.

I think other Chromebooks may actually be easier. Notice that the Intel Sound Firmware deb has many different chipsets included. The 5.xx kernel also has many fixes already in it for hardware. And many of the UCMs are already in place. So I think we're close to opening up Chromebooks as viable Puppy boxes now.

If there is an incompatibility, I now know a lot more about these problems, and can probably solve them easier. More than I wanted to know.... Laughing

Yes, this is more than we should need to know about Chromebooks Rolling Eyes Laughing Laughing

I posted a correction for your step 2.
Should be /usr/share/alsa/ucm/chtmax9890

Nope, it's 98090. At least on the R11.

Yes it is 98090. Embarassed

I was actually pointing out that you left out the alsa.
Should be /usr/share/alsa/ucm/chtmax98090

vtpup,

You getting sound OK in a browser?

I am using Pale Moon and get no sound.

Really strange.
With the browser running.
Multiple Sound Card Wizard->Test sound will not work. Shocked
Shutdown browser and the test works Rolling Eyes

Deedbeef sound works.

With all those Retrovol Mixer settings.
Probably, something not set correctly, maybe!

Same problem here with Seamonkey.....

Interesting, because other programs like, mpv play movies (with sound) fine.

I thought it might have something to do with needing to specify apulse when invoking the browser, but that doesn't solve it.

I still wonder if pulseaudio is part of the problem with current mozilla based browsers. Seamonkey 2.53 definitely has switched to the recent firefox engine that requires pulseaudio.

ps, don't mess with the mixers, too much, ESPECIALLY DC Speaker Blocking (as I'm guessing that one may prevent speaker melting problems mentioned earlier).

Also thanks for the alsa correction, I edited the post.

Could you try it with Pale Moon browser?

I stopped using Firefox and Seamonkey a long time now.
I am sure apulse is needed for Firefox.
Bionicpup64 8.0 has already got the apulse stuff, for the Firefox, you can get from Quickpet.

I do have Bionicpup64 8.0 updated by Quickpet->Info->Bionicpup updates.
