dac8 Stereo v1.2 firmware now available for download with instructions at
https://www.oktoresearch.com/dac8stereo.htm.
Anybody try it yet?
I installed it more because it's the only way their dedicated ASIO driver will work (compared to the previous DIYINHK drivers they used to issue).
There are also a few more controls that are specifically geared to measuring.
IN MY CASE, I had the following issues:
1. Initial attempts through Windows 11 would appear to fail (looked like nothing was happening). Because of this, I noticed the samples of the process was via the Command Prompt screen, so I tried the update via Command Prompt. It still failed, but now I could see why.
a. It was able to see/find the dac8; however, there was something about either the existing firmware (1.12) or the board build that made it not work (see attached) - not clear what it was referring to with "1.50."
2. Emailed Okto, and Pavel said to try the "other OS" method (using Mint Cinnamon), and that worked - on the third attempt.
a. The first two times, it failed right after the "USB firmware upgrade done." It would not get to the "front panel upgrade" part and the unit would remain at 1.12.
b. The third time everything went through fine, and it was updated to 1.2.
I don't know what made me try 3 times - dumb persistence, perhaps, but I'm glad I did.
I emailed my experience to Pavel, and he surmised that the Windows attempt may have borked something that caused the Linux/Mint method to fail a couple of times...maybe. Realistically, if you already have Linux, it will probably work just as well. I can't imagine there's something about using Mint that would make it work better otherwise. I just opted for Mint because it was the method recommended, and no matter which distro I used, it would have to be via USB boot anyway.
