Do you have another OS on this machine (Windows, Linux…) where the sound chip is working? If yes, you could try to boot into that OS first and then do a warm reboot into Haiku and check if the sound is working. Not really a practical solution but if it does work (with the hda driver, that is) please report it on the ticket I linked, it might help the developers find the problem.
Regarding OSS, did you check that you disabled the hda driver correctly? Blacklisting is explained in detail here: Disabling components of packages | Haiku Project . It’s important that not both the hda driver and opensound are active at the same time.
Furthermore you can upvote the ticket in the bugtracker. This doesn’t guarantee anything of course but might improve the chances of the ticket getting worked at.
You could also boot from a live Linux distro on USB stick and then reboot. I used to do this with a laptop that just had Haiku installed but the same HDA init problems.
I booted another OS where there is sound. The problem remains. No success with disabling the package. Thank you for your time.
After disabling it I still get two drivers
