Audio in VM with Volumio

[sadek]

Here I am with another question.

I created a VM with the Volumio distro for x86, the machine starts up and runs, but I can't get the audio to work properly.

Using the command speaker-test, I can hear audio from the two sources.

Using the command aplay -l, I get this:

**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 0: ALC3236 Analog [ALC3236 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Is it possible to hear the audio?

Hi,

Is it possible to hear the audio?

Yes, are you running your VM from SPICE [1]?

I followed the steps of the link you gave me. What should I check?

 

[Moayad]

Could you please post VM config qm config <VMID>?

Hi again,

Please try to change Audio Device to intel-hda then stop & start the VM, and see if works.

I get this error on Volumio;

Failed to open "alsa" [alsa]; Failed to open ALSA device "hw:0,0": No such file or directory

 

[Moayad]

From Proxmox VE go to Datacenter -> YourNode -> VM -> Options edit Spice Enhancements and select Videostreaming [1] and from Hardware edit Display and select SPICE then try to hear in Volumio.

Tried, but I get the error mentioned earlier

 

[Moayad]

Is the Proxmox VE server locally? - you can get sound locally on the built-in sound card, by giving it to the VM as a PCI device [1]

When I give the command to check if iommu has been enabled I get this:

root@sadekserver:~# dmesg | grep -e DMAR -e IOMMU -e AMD-Vi
[   18.877312] AMD-Vi: AMD IOMMUv2 driver by Joerg Roedel <jroedel@suse.de>
[   18.877316] AMD-Vi: AMD IOMMUv2 functionality not available on this system

Is my device not compatible?

 

[Moayad]

Is AMD-Vi activated in the system's BIOS?

It's an older laptop with AMD A4-5000, and in the BIOS I don't have any options to enable, it's very basic
