A Sound Question

Here was my impetus in choosing the card(s) to upgrade to Mojave:

How to upgrade to macOS Mojave - Apple Support

Of course this was based on the install intercept saying I had to have a Metal capable Graphics Card

Mac Pro introduced in late 2013, plus mid-2010 or mid-2012 (mine) models with a recommended Metal-capable graphics card.

"These specific third-party graphics cards are Metal-capable and compatible with macOS Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012):"

• MSI Gaming Radeon RX 560 128-bit 4GB GDRR5 ( Tried it - No Sound - returned)
• SAPPHIRE Radeon PULSE RX 580 8GB GDDR5 (Currently installed and Sapphire belatedly telling me no audio support)
• SAPPHIRE Radeon HD 7950 Mac Edition
• NVIDIA Quadro K5000 for Mac
• NVIDIA GeForce GTX 680 Mac Edition

The rest, below the RX580, begin to get into the $$$ range. As an Apple believer, I'd have assumed (yes, I know) that these had been vetted and would be a lovely plug-and-play to bring Mojave to your Mac. And why would I begin to question the potential for issues with audio output? After all, Apple says these are 'good'...... and all of them eclipse the performance specs of the original ATI Radeon 5870 I removed. 'Shoulda' been a slam dunk. HDMI to HDMI and modern technology at its finest.

Now waiting for the aforementioned adapter to see if I can patch it sideways and make it work.

"You could use a HDMI Audio Inserter, such as

to add optical audio to the HDMI from the graphics card." From Malcom's reply.

And, if not, use the clone drive to return to High Sierra and put the ATI back in. Or decide to invest even more and see if there's a capable audio/video/Metal card that will only set me back a car payment or two....

And Sapphire Tech says:

The HDMI Kext is installed. Unfortunately, there is no additional HDMI port on the Comcast box. It's the Xfinity system with small satellite boxes next to each of the TVs beyond the main box.

Looking more like a last ditch call to Sapphire and then maybe a new trial TV to see if that works.

I have been hoping it would show up. I have only seen the model of the TV in the Color Profile prefs from the old original graphics card, but never as a sound output choice. I've rebooted at almost every change of setting or hardware change.

The only time I get sound is using a DVI adapter out to HDMI, and using the 3.5mm patch cord from the Mac to the TV. BUT, then the picture goes garishly purple cast and won't adjust no matter how many settings I change. Line out works for headphones and speakers.

Expensive thought, but could this TV be beyond its years for the graphics card to register it? The TV works fine on TV mode with the cable box. It's about the only other change I have not tried, save calling Sapphire Technologies tomorrow when they're open, which I will do next, I guess.

I’m bummed and have had no success after the installation of the 1.1 version. I think it may be cheap tv trial purchase time.

It’s amazing that the old Amd Radeon cars using dvi and line out worked but this does not.

I've done this and still have no HDMI selection for Audio.

It appeared to have no trouble installing. Any difference for Mojave vs. High Sierra?

Thanks, I'll give it a try. Have one on order and now beginning the email rounds of fun with Sapphire.
