No Volume control with HDMI audio

[niceman1313]

Hello , thanks to this forum i have a near perfect hackintosh laptop for which i'm very thankful!

Now there's just one little thing that makes my hackintosh life a little harder; I have no volume control over my HDMI (only audio output) channel. When i press any volume key , a "blocked" icon appears where the volume bars should be.

I followed instructions posted somewhere buried in a post by Feartech, he said in order to get HDMI output working you first have to get onboard working. For this, he referred to MironeAudio HDApatcher and this enabled my HDMi audio and nothing else. That's fine however, i only want to use HDMI audio.

I'd just like some control over my volume with the volume keys on my keyboard instead of getting the receiver remote.

Did i take the wrong route by doing the HDApatcher by Mirone? As far far as i've read, HDMI audio patches work by changing the port in frame buffer to a HDMI one ( 000040000 to 00080000) but i have already done this to get my HDMI working in the first place.

Problem reporting files are attached!

It is as per Apple design. A real Mac would have the same result.

Fair enough.. Is there any hack around this apart from fixing onboard aux? I've tried adding virtual audio devices in MIDI audio setup, but would give me the same result. If not, i guess one can't have everything he wants
Thanks for your quick reply!

I think there are some 3rd party software that can do it.
Google might help you find it.

Hello @niceman1313,

I had the same issue like you and found a 3rd party app called Soundflower and Soundflowerbed which is working fine so far. Is a kind of bypass for the audio driver and let you control the HDMI or Display port audio.

Regards

Hello GMarrara ,

Thanks for your suggestion.
I had come across Soundflower(bed), and was quite happy with it! The only problem i had come across is that it drastically lowers sound quality.. The noise floor is higher, and more easily distorts at somewhat higher volumes. So i just ended up using the AV-Receiver's remote
