Mac Mini 2010 - Nvidia 320M nouveau -> no HDMI audio

mint_user45 · Post by **mint_user45** » Tue Sep 21, 2021 11:44 am

last try before giving up , I've installed last Mint Cinnamon , I use the nouveau open source driver that claims to support Nvidia 320M HDMI audio

analog audio works fine, HDMI audio with proprietary driver works but I'd like not to use it because is discontinued (not supported with latest kernels) and makes the OS unstable

I've tried the usual stuff and I'm sure it's not a problem with mixers, muted audio etc.. In the pulse mixer I can see the hdmi audio available, cable plugged in etc.. but no audio through HDMI till I switch to the internal speaker (the mac mini has a very low quality internal one )

Any idea?

Thanks

Welcome to the forum, mint_user45.

With a Intel Core2 Duo P8600, I recommend you stay with the 5.4 LTS kernel in Linux Mint and not use the 5.11 kernel. Your computer has older hardware and an older kernel is usually a better match for it. If you need instructions for switching back to the 5.4 kernel let us know (and also let us know if you are using grub).

Actually, the Nvidia-340 should work well with the 5.4 LTS kernel which is supported in Mint until April 2025.

For troubleshooting audio issues, we recommend installing pavucontrol which gives more options for troubleshooting. Have you tried that?

mint_user45 · Post by **mint_user45** » Thu Sep 23, 2021 11:00 am

thanks for answering,
yes, I've installed pavucontrol and tested all the configurations. I can stick with 5.4 kernel , the problem is that I had a lot of strange hw problems (random crashes during boot, ethernet randomly dropping connection etc...) that vanished once using the open source display driver. I'm not a gpu power user and just use linux for development so solving this last problem with HDMI audio would have been great .

BTW I'll give a last try to the nvidia driver with 5.4 and if I start having problems again I'll buy a soundbar

mint_user45 · Post by **mint_user45** » Fri Sep 24, 2021 3:08 am

what puzzles me is that I can see the audio bar moving like there's audio sent to the monitor but still no sound (I also checked all the checkboxes in advanced just in case)

Post by **SMG** » Fri Sep 24, 2021 5:39 pm

I did some research and it appears that in either case (Nvidia or nouveau) the driver for sound is the same (below). The graphics driver does not control sound. While the name has intel in it, it applies to all (nvidia, AMD, and Intel).

Code: Select all

alsa.driver_name = "snd_hda_intel"

Maybe something in this thread No sound on HDMI Ubuntu 20.04 might help, although I would think whether or not you have sound should be the same given the sound driver is not changing when you change graphics drivers.

Hello mint_user45,

Your pavucontrol screenshot looks fine, but check the Playback tab while trying to play sound. It could be muted or have no volume there which will cause exactly what you're experiencing even though the Output Devices tab makes it look like everything is as it should be.

I'd agree but when I install the native nVidia driver I could hear sounds through HDMI and the Nouveau feature matrix mentions HDMI audio (TODO->DONE), in case of 320M (NV50) is supported

https://nouveau.freedesktop.org/FeatureMatrix.html

that's why I'm still struggling but with 0 results so far

thanks in Output devices I can see the bar moving while playing audio and the HDMI3 cable plugged in (the others HDMIx are unplugged), I tried restarting with

Code: Select all

pulseaudio -k

I can see the screen updating but still no audio

That square of the grid says DONE, but it has a superscript 10.
Superscript 10 says "HDMI Audio only works for NVA3/A5/A8 (GT21x) GPUs. Some pre-NVA3 setups have been reported, but it's no thanks to nouveau."

On this page listing the NV50 Family, I see the GeForce 320M listed for NVAF at the very bottom of the grid on its own line and not listed with the NVA3/A5/A8 (GT21x) GPUs.
NVAF (MCP89) - GeForce 320M

you're right I did not notice it

Just in case there's still something we can do, let's get a look at your sound setup with this command:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

Please run that while trying to play something with sound.

We didn't get all the info I was hoping we'd get. Please run this one now, and paste the URL it'll give you after you select the upload option over save locally:

Code: Select all

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

You can also change pavucontrol's Configuration tab setting to Digital Stereo (HDMI 3) Output + Analog Stereo Input and see if that makes any difference. It shouldn't help, but weirder things than that have worked before.

I am having the exact same thing in checking with the Pulse Utilities on a newly installed Linux 20.2 on a iMac 15,1 today! It is the strangest thing so I know exactly how perplexing this is (it has been driving me up the wall). I am still at the early days trying to figure this out but if anything of relevance comes along I will be sure to post.

I don't see anything obvious to indicate why the sound isn't working. However, right near the bottom I saw this that I don't usually see:

Code: Select all

[   11.193434] snd_hda_intel 0000:00:08.0: position_fix set to 1 for device 10de:cb89

I guess we'll try setting the position_fix to 2 and see if that makes a difference. Here's the command to run:

Code: Select all

sudo tee /etc/modprobe.d/position-fix.conf <<<'options snd-hda-intel position_fix=2'

Run that in the terminal then reboot and test your sound. If it was of no help, you can remove it with this followed by another reboot:

Code: Select all

sudo rm /etc/modprobe.d/position-fix.conf

Were you having stability issues when using the 5.4 kernel or just with the newer ones? The Nvidia-340 does not have support for the newer kernels, but it should be working with 5.4.

version >5.4 simply crashes. With 5.4.x it kind of works (for example in this very moment i'm using 340 and the HDMI audio is perfectly fine)

BUT

it does not start all the time .. let's say if I restart 3 times , 2 times it simply hangs so that I've to reboot and cross fingers, like there was a race condition somewhere and when it starts, sometimes I get some random issues to the ethernet driver.. like it disconnects for 2 seconds then it connects for 2 seconds etc.. most of the time it just works. Perhaps I could investigate further opening another thread, let's say I prefer sticking to a stable system with no HDMI audio than to an unpredictable one with audio

I feel you pain. I spent all day banging my head against the wall with my similar issue. In the end I think that it might be easier to get a USB external sound card that's properly Linux compatible with ALSA. I'm just glad they exist! I had no idea they did till this issue. That is the way I am thinking of going, given they don't look expensive and would allow me to have sound that isn't doing exactly what yours is doing. Temperamental sound is a pain in the backside and these Mac specific idiosyncrasies are too common on Linux by the looks of it.
