Sound does not work

Rocky Linux General

I have performed an installation of Rocky 8.4 in a Centos 7.9 hyperviser. Everything went well except i can not access the usb ports and the sound is not active. I have the sound set to ich6. Your help would be apprecated.

I was able to figure out the usb problem, I just need to authenticate the usb with the hyperviser.

I still have not been able to get the sound to work. I would sure appreciate your help.

Rocky 9.2 VM Web Server

Looking for the same solution for the no-sound from the VM, has anyone solve this? I added “Sound ich9” and its set to HDA (ICH9) with no success.

From: lspci -v

What do I need to do to make this work?

Has anyone solved getting Guest VMs sound to work? And what is openSUSE Leap doing different then other RPM base OS doing to successfully get sound to work?

do you have qemu-guest-agent or equivalent installed.
In proxmox on one of my vm’s i just added a sound device (proxmox uses qemu vm’s)
and I already had the /usr/bin/qemu-ga running

/usr/bin/qemu-ga --method=virtio-serial --path=/dev/virtio-ports/org.qemu.guest_agent.0 --blacklist=guest-file-open,guest-fil
e-close,guest-file-read,guest-file-write,guest-file-seek,guest-file-flush,guest-exec,guest-exec-status -F/etc/qemu-ga/fsfreeze-hook

and my audio device is as follows.

02:0c.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
Subsystem: Red Hat, Inc. QEMU Virtual Machine
Physical Slot: 12-3
Flags: bus master, fast devsel, latency 0, IRQ 36
Memory at fe600000 (32-bit, non-prefetchable) [size=16K]
Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel

in other words it does not have the Capabilities: <access denied> that you have.

i cant test that the sound works for you but the change in the status between my system and yours if you dont have the /usr/bin/qemu-ga may be an option to try.
