Stupidly I installed 1.2 immediately after getting the message instead of waiting a few days. Well, it didn’t work, even after a complete restart of my Mac. There is serious distortion with hirez and 44.1 KHz files. Re-installed 1.1 and it works again.
Have you stopped to consider for a second the problem might be on your side. Is your dirac’s capabilities being detected in setup…if not it may be its driver does not accurately report the dirac’s playback capabilities…Roon requires the driver to report the devices capabilities, which was not the case in 1.1
Took the plunge and tried 1.2 again. Everything set correctly and Dirac’s abilities detected again resulted in distortions. Enabling “Use Power-of-2 Hardware Buffer Size” in zone settings helped.
Can anybody explain why in v. 1.2 there are more details and settings necessary than in v. 1.1?
What exactly is this Hardware Buffer Size and which hardware does this refer to?
The increased details and settings include more problem solving options. Some of these are included because of hard won experience with odd choices made by other hardware/software engineers. Some of them arise from the new audio system introduced with 1.2. In 1.2 Roon asks devices what they can do and implements outputs based on the answers. As devices become better at reporting their capabilities, this will be a better long term foundation. But at the moment there are devices which frankly lie and others which hide their talents under a bushel. Some of the new options assist in dealing with such ill-mannered behaviour.
The KB article linked by Vova above sets out what every setting does. If it is a problem solving setting and you don’t have a problem, just leave the default.
Think might be an odd sort of red herring - seems to be an issue with Hey Now 24bit by London Grammar - looking at the flac file it is limiting big time. I have now tested other HD files which are fine. Odd that the same file played via Airplay sounds fine. I am going to dig out my London Grammar CD to check that.
