Problem with ROON

[markush]

There is a problem for Devialet users with the recent ROON version. See https://community.roonlabs.com/t/music-p...app/183093

What SAM setting are you using, is it 0%?

For some reason if you have SAM set to 0% it does not show in the Signal Path info. Once you increase the SAM setting to 1% or greater it shows and once you reduce it again to 0% it stops showing. It's been this way for I don't know how long, at least a year or more, and it hasn't changed with the latest version. The current version is working fine on my 140 Pro and it's working exactly as I just described which is exactly how it's been working for months, over quite a few versions.

I don't know it it has always been this way but I can't remember it being otherwise since we got the original update which allowed us to use RAAT.

Hi David,

oh wow you nailed it! I just started using SAM with 0% and that’s why I thought build 884 of ROON is no longer showing it.

But one other thing is different: it used to show which speaker SAM profile is being used. Is it showing this information still?

[Jean-Marie]

And still, I would consider a bug not showing SAM when it is at zero percent, because it is still correcting the phase!

Yes this is definitely wrong and should be corrected by ROON.
Do you see the loudspeaker SAM profile? This is another bug unfortunately.

I added a new thread mentioning the two bugs:

Yes, when I tap on the SAM stage in the signal path, I see that the SAM profile is for ARMONIA, which is my speaker model, as shown below.

I'm not certain that the failure to show SAM at 0% is a Roon issue, it may be a Devialet issue.

What Roon shows in the signal path is a combination of what Roon is doing and what the Roon Ready end point reports that it is doing. If the Devialet does not tell Roon that SAM is active at 0% then Roon will not show SAM in the signal path info.

Perhaps Roon made a decision not to show things like tone controls and SAM in the signal path info if the setting was zero, or perhaps Devialet don't report zero settings to Roon so Roon can not display that info. We simply don't know whose problem it is. Since the issue has been posted on the Roon forum I suspect we'll hear something from Roon much sooner than we could expect to hear something from Devialet who don't seem to like communicating publicly with their customers.

Should be easy to test. Set SAM to something non-zero and see if it turns up in Signal Path or @Jean-Marie could maybe try his SAM setting at zero and see what happens...

I confirm that if I dial down SAM to 0%, Roon incorrectly removes the SAM step from the audio path. 

It reappears as soon as I dial it back to any value other than 0.

@David A, you are absolutely right, we have no way to tell who is the culprit between what Devialet reports and what Roon does with the information.
