HD Audio is generally more capable. Last modified 9 years ago. I believe I have discovered the cause of the problem. It is up to software whether to disable the rear panel audio output when a connector is plugged into the front panel output. Bookmarks Bookmarks Digg del.

Click on the Windows Button and type regedit into the text area. Guest Windows reports that no audio hardware was not detected, most probably the Plug’n play descriptors reported by the emulation driver is not correct or is not correctly virtualized.

So the reason is somewhere else, and the response about missing bit support is not relevant. And keep in mind that we chose the ICH controller 4 to 5 years ago. I will be adding emphasis. Forget the erroneous “6” that I added inadvertantly after “ICH”.

Let me start out by asking an important question. I’m not sure of the exact different I assume that HD audio will gives better icy quality but I’ll always go for HD audio if the mainboard has it, if the mainboard only has AC97 then I’ll use AC97 connector. I still have not received answers that will help me proceed with testing.


With this latest round of testing the Ubuntu I discovered that the Volume Slider problem exists even after the clean install of Virtual Box 5.

I don’t understand this response. How VMware Workstation solved this problem? I saw in previous updates IF ELSE Statement extracted from Patch code and it is not clear whether this was original code from the patch that needed modification or if the code logic was already changed to reflect the prevent switching mentioned. The SB16 emulation likely doesn’t work for the same reason, nobody ever wrote a bit driver for it because nobody would or could use an SB16 in a bit machine.

If it is supposed to be working then please continue reading ixh response. Are you supporting power management states described in the ICH specifications for powering on the device only when it starts ad97 usedor do you assume that these virtual devices will be always on and that the guest’s driver will not verify it?

HD Audio or AC97 connector – Which to use when, and what’s the difference? – Super User

Otherwise, I a9c7 track this issue and hope that some day it gets resolved. But set it to nullaudio. Will check with pulse and report back.


However there is nothing coming out of the speakers. Use instead this direct link which is much more reliable: I tried with and without the guest additions and I also tried SoundBlaster 16 with and without the guest additions.

In particular the handling of plugging in of front panel devices is different. I would recommend the development team research the differences of how Audio is treated across the platforms that fail vs the ones that work.

Most users aren’t going to find that acceptable. Alberto Salvia Novella ese on These are just a few examples, but they don’t always report this in the marketed product type, when they judge that the disabled feature is not essential for their market, or when they can provide workarounds around some common defects.
