hhfeuer / nvhda Goto Github PK

Hello!

Could you give an advice about how to set up this module to work together with optimus-manager properly?

I have a laptop that supports Optimus technology.
I installed optimus-manager and use it to switch between Intel and Nvidia GPU.
I've installed your module as well.

The issue is that upon switching to Nvidia card, regardless of the nhvda enabled I still can't see my second audio card in the output of aplay -l
In order to enable it, I have to switch off an then switch on back.

I think about some sort of script (or systemd unit) that will check with which GPU system loaded and enable nvhda if required.

Is it good enough solution or could be better?

The output from dmesg is that no audio device is found. I have since reverted to the previous NVidia driver (430.40) and its working again. Fedora 30 - HP Omen with 1060.

Dell Precision 5520 with Quadro M1200 4GB. In case it is relevant, I am using mvidia-xrun on Arch lInux (https://wiki.archlinux.org/index.php/nvidia-xrun).

Enabling nvhda fails here:

yet in my limited understanding the multifunction bit is set (see 0x80 at offset 0x0E at the very bottom).

To save some others some struggle (took me two days to figure out):

BIOS Display set to Nvidia Optimus
Install hhfeuer/nvhda (this github)
sudo apt purge nvidia*
sudo apt install nvidia-340 (later versions did not work for me)
reboot
configure pulseaudio to use HDMI output device

Hi there! I've tried to compile nvhda on Arch with kernel-5.6.3-zen, gcc-9.3.0 and make-4.3., but the following error occurred:

I managed to compile successfully with the following patch.
nvhda.c.patch.txt

Hi, great job, really appreciated. I am wondering how to modprobe the script automatically at every boot while setting the variable to ON by default. It would be much better than manually do it every time.

Many thanks again!

Used to work well on Ubuntu 16.04, 18.04 and 20.04 (with re-install), but when the drivers upgraded to 460, there comes bugs.

Basic conditions: Thinkpad P51, Ubuntu 20.04, with nvhda-start.service in /etc/systemd/system and nvhda in /etc/modules
After boot, journalctl -u nvhda-start.service shows that the service is started successfully. Terminal shows:
Input:

Output:

It seems like the audio hasn't been real turned on. I tried to turn it on manually with sudo tee /proc/acpi/nvhda <<<ON, nothing happened.

Nevertheless, in the same condition after boot, if use sudo tee /proc/acpi/nvhda <<<OFF before sudo tee /proc/acpi/nvhda <<<ON, the audio can be turned on.

Therefore, I tried to add /bin/echo OFF >/proc/acpi/nvhda in the nvhda-start.service, but failed to fix this bug.

However, I'm not sure whether this bug comes with the latest driver or some other reasons. It's just a possible cause.

Hello,

Together with the Kernel Update 4.20.11 I had to do a complete Reinstallation of the Nvidia Drivers to Version 418.43-2. (Nvidia seems to have decided out of the Blue to move my Graphics Card out of Legacy 390xx to the new Version, after moving it to Legacy just a few months ago...)

I have a Thinkpad W530 using a Nvidia Quadro K2000M. And Nvhda was working perfectly with Nvidia-390xx since October 2018.

• I removed the Kernel Module from DKMS
• Removed Nvhda with yay -Rs nvhda-dkms-git
• Rebooted
• Reinstalled Nvhda from AUR

'sudo modprobe nvhda' seems also to run through fine. No errors there.
Then to switch on Nvhda also seems to run with 'sudo tee /proc/acpi/nvhda <<<ON'

But even though anything looks fine, I cannot get Audio through Displayport anymore. Config of Bumblebee hasn't changed at all.

dmesg upon enabling nvhda gives me:
[ 2659.797670] nvhda: Found nv audio device 0000:01:00.1 [ 2659.912007] pci 0000:01:00.1: Dropping the link to 0000:01:00.0 [ 2659.912019] nvhda: disabling audio [ 2664.481122] nvhda: enabling audio [ 2664.481160] pci 0000:01:00.1: [10de:0e1b] type 00 class 0x040300 [ 2664.481195] pci 0000:01:00.1: reg 0x10: [mem 0xf1080000-0xf1083fff] [ 2664.481521] nvhda: Audio found, adding [ 2664.481532] pci 0000:01:00.1: BAR 0: assigned [mem 0xf1080000-0xf1083fff] [ 2664.481572] pci 0000:01:00.1: Linked as a consumer to 0000:01:00.0 [ 2664.481760] snd_hda_intel 0000:01:00.1: Disabling MSI [ 2664.481771] snd_hda_intel 0000:01:00.1: Handle vga_switcheroo audio client [ 2665.057288] input: HDA NVidia HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input44 [ 2665.057453] input: HDA NVidia HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input45 [ 2665.057662] input: HDA NVidia HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input46

Are there any logs by Nvhda to Look up or anything else I can provide?

Edit: Noticed something else weird. If I use Alsamixer the Nvidia Card is detected after turning on Nvhda. But switching is impossible. Graphics card is not shown anywhere else. Gnome Settings just show Internal Speakers.

Hi, I found this solution, and it worked. Then, after a reset of my pc and reinstall, the audio control shows my Nvidia card, but the profile remains always "OFF"

Hi, I still need nvhda on

Could you please give me a hint how/whom to notify of the missing PCI quirk following your README remark?

In the nvhda-start.service file, do I need to add modprobe nvhda before /bin/echo ON >/proc/acpi/nvhda?

Hi, man, how are you?
I discovered this week that my hdmi has no sound. I found your repo and installed this module in my ubuntu 16.04, kernel 4.15. After installing the problem is that even connected with hdmi now it does not display anything. What should I do?

Kubuntu 18.04.02
nvidia 1050 TI (390.116)
Turn audio on by sudo tee /proc/acpi/nvhda <<<ON, set GP107GL as default output.
Suspend laptop, wakeup and OS has audio off.
If I execute again sudo tee /proc/acpi/nvhda <<<ON, back GP107GL as default output.
Can I fix it?

Hello,

I have a laptop with 2 GPU and use an optimus-manager to switch between inte/nvidia GPU.

For some reason after switching to NVIDIA and turning on nvhda, I can't switch the audio output to HDMI.
HDMI output appears in a list of audio devices, however after switching to HDMI nothing happens, and I can't see any errors and nothing suspicions in dmesg...

What could I do to debug this issue and find out what goes wrong?

Arch linux, kernel - 5.1.15

..and hdmi audio is not enabled.

How can I fix this? Thanks!

Hello!

I just wanted to report, that I am still using your module, despite having Kernel 5.7 on my Manjaro system
The reason is that after every suspend my system defaults to nvidia's hdmi audio output. I tried about 10(!) different methods for configuring this output as not default in pulse or disabling this output completely, as I don't need it at all - with no effect at all! The nvivida hdmi audio output inevitably takes priority once it's loaded!
So I created a systemd.service as a one shot, that uses your module for disabling the output automatically after every suspend or boot.
It's annoying having to do such workaround, because of the stuborn nvidia driver, but I am glad that the module is there and still working, and I hope it will continue to do so.
Thank you! :)
