How to make audio device settings permanent, or disable auto audio device discovery?

Hello

I’m looking for a way to keep my Audio settings permanent. Every time my AVR is turned off, the settings reverts to “Auto select device” and stays this way, even when my AVR is turned back on.

It makes a huge difference on the sound quality, and I don’t want to set this every time I turn my AVR on.

I’m not afraid of advanced configurations, but if there’s a way, I don’t know it.

Actually I found the part of the logs where the switch is done when the AVR is stopped. Maybe there’s a setting to disable this auto-detection?

And when I re-enable it :

So maybe theres a way to fix this property audio-device="wasapi/{184dbba3-efc4-40c2-9da3-8078488c955d}" -> 1? Making plex.ini as read-only don’t works.

Thanks!

I have had this same question and not received a real response.

One suggestion is to use something like a Gefen HDMI Detective. When you have this between your HTPC and your AVR, the HTPC will always see the EDID of the AVR. This should solve your problem, but note that if you remote desktop into your PC or unplug any of the HDMI cables it will revert settings.

You might also try the new HTPC Player (link below). This player is a bit easier to go and change these settings back, and also seems to take effect immediately. I recall needing to restart the Windows Player to get the audio settings to actually take effect.

Good luck!

We added a behavior to the HTPC app which reselects the previous device. I’ve filed a task to bring the same behavior to our Desktop app as well. There’s quite a bit of work in line ahead of it making it hard to understand when the change would be released.
