Has anyone been able to get a sound card working on ESXi (I’m using 7.0) using PCI passthrough?
I have created a VM using the OVA image and added the sound card (SB1570 Audigy Fx) as a PCI device. Everything seems to work just fine, except the sound card is not detected. I cannot find much of interest in the logs, other than notices that no cards were found.
Creating a VM using the VMDK file behaves identically. However, an Ubuntu VM is able to detect the card without issue, so I do not think it is a fault with ESXi.
The following may not be relevant, but it is where I’m at…
Ubuntu appears to be using the snd_hda_intel module to load the card, but that module does not appear to be loaded in HA. Actually, lsmod only lists a single module, xfrm_user. Is that true, or what am I missing?
Looking at the operating-system source for the nuc, I see the follwing entries in buildroot-external/board/intel/nuc/kernel.config:
CONFIG_SND_HDA=y
CONFIG_SND_HDA_CORE=y
CONFIG_SND_HDA_GENERIC=y
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_I915=m
CONFIG_SND_HDA_CODEC_REALTEK=m
CONFIG_SND_HDA_CODEC_ANALOG=m
CONFIG_SND_HDA_CODEC_VIA=m
CONFIG_SND_HDA_CODEC_HDMI=m
However, the corresponding OVA file (operating-system/blob/dev/buildroot-external/board/intel/ova/kernel.config) does not have any CONFIG_SND_ entries.
I tried loading the snd_hda_intel module using the instructions found here. The .conf file is created in /etc/modules-load.d/, but I do not see that the module is loaded.
Is the snd_hda_intel module actually being used and I’m looking in the wrong place? If it is not loaded, could that be my issue? If so, how do I proceed?
My apologies in advanced if I’m way off base. This is well out of my realm.
Edit: Yes, I can probably install HA using docker in a VM, but I’m stubborn, I feel like this should work, and would really like to understand what is going on.
