PO3-655 reinstall DTS Sound unbound and Ultra because both these apps are uninstalled

Sunnycoast · February 9

My daughter uninstalled both these apps.

I tried to reinstall the Realtek driver but nothing.

The individual downloads on the product page for Unbound and Ultra have no setup files, just scripts that failed to run.

Sound Unbound is on the MS store but not Ultra

[Edited the thread to add issue detail]

I found some info on this support forum with excessively complicated instructions that didn't actually work - using the ACER DTS downloads for my desktop.

I then decided to just install DTS Sound Unbound from the MS Store and it showed an active license.

DTS Ultra X was not showing in my MS Store but found a direct link in a forum and installed it - it also showed as licensed.

A lot easier than the Acer method, which didn't work.

The drivers and software in my Acer Product page are 12 moths out of date as well - even though they were listed as Jan 2023 ! MS Update had much more recent drivers.

All Acer support drivers for your desktop are the oem drivers that Acer used when the desktop was released but its especially there for the bios and firmware updates, whcih you should keep a track of and in your PO3-655 desktop case, its the same as the PPO3 650 dsktop, as the PO3-655 is just a nwer version of that desktop, Win-11 will keep the majority of the drivers up to date including some firmware. If you want, you can also update the NVidia drivers yourself with the NVidia GeForce Experience software that not only notifies you of new NVidia drivers but also has specific NVidia settings for over 1500 games that you might play on your desktop. The audio drivers are not only governed by the Realtek driver, the audio driver is also affected by the NVidia audio drivers which and if your audio is to work, the NVidia audio drivers also need to be updated and not corrupt. I suggest that you reinstall or get the NVidia driver up to date, as then your audio should work including the DTS which is a sound enhancer that most users don't use, use the free FXSound because its just as good if not better. Good luck.

The Version 4 of Predator Sense for my PO3-655 fails to recognise the fans etc so I have to use the previous version.

Acer has dated drivers for my 655 on its product page as Jan 2024 and as you say, are 12 months old.

I would not trust any BIOS update from Acer based on those issues with their provided drivers.

The Sound Unbound and DTS ultra packages offered on my product page don't work with script errors.

I don't feel like bricking a week old system with poorly written BIOS.

I still remember Acer Support wanting me to wipe a day old system because Version 4 of Predator Sense wouldn't detect fans on the Desktop. They then wanted me to send it to them. Seriously….

Please note my audio works just fine. That isn't the issue.

I just wanted to reinstall DTS software that came with the Acer.

I use the DTS licenses to upmix certain content to my AVR and HT system via HDMI.

The NVidia audio works perfectly fine and is totally separate to the Realtek drivers. I updated to the NVidia GPU and HDMI audio drivers as soon as I got the Acer as Acers were old.

If this is how you feel about the Acer bios and firmware for your desktop "I would not trust any BIOS update from Acer based on those issues with their provided drivers" then go and flash your PO3-655 bios with another bios version other than an original Acer bios and see what happens, as you will brick the bios chip and you will need to get the bios chip reprogramed. That is a very bad and negative attitude and thinking like that you are asking for major troubles with your PO3-655 desktop. Good luck.

Why would I use another BIOS ?

I never suggested anything like that ?

I'm suggesting that if Acer can not get basic drivers and software correct for my desktop, I definitely would not trust BIOS updates from them.

Suite yourself and don't update anything from Acer especially the bios and firmware of your desktop, but please don't come to this forum and start complaining about issues that a new bios updates FROM ACER fixes. Good luck.

I might be wrong but I think DTS Unbound replaces the DTS X Ultra as Unbound is readily available and I cant find the DTS X Ultra for download anywhere.

Acer comes with a one year warranty and rarely do they ever release more than a single Bios update and drivers get handled by Windows. Mind you early windows drivers meaning ones released after your systems initial drivers can break things but after the hardware has been out 1.5 to 2 years the newer drivers should be safe to use thus Windows 10 or 11 just updates them in the background during an update. Intel has their own driver software so does Nvidia and AMD. as far as Bios you might find an unlisted update for the board model number but if you chose the wrong one per accident or from a malicious source you will have a brick machine.
