Welcome Mosaic 1.1.1

[aublumberg (Andre Blumberg)]

New Bartok owner - 2 weeks and counting. Upgraded to 1.1.1 immediately and experienced 3 hangs / freezing of dCS display in various situations over last couple days. One symptom is unit total unresponsive (need to power cycle), one is where screen shows 2 titles ago and frozen and no button response but music still playing and accessible on dCS Mosaic. Third symptom is dCS Mosaic unresponsive. Mostly concerned about the former two - is this common? Any tips to root cause analyse / rectify this? Thanks!

@aublumberg

is this common?

Welcome Andre. The problems that you are experiencing are not common. When you upgraded did you first turn off the Bartok and wait a few minutes before rebooting and then perform the update? Would you kindly confirm which software version is displayed in Mosaic for the Bartok and which software version does it show for the Mosaic app?

[aublumberg (Andre Blumberg)]

Thanks Pete. Well, I upgraded the firmware as the first step after unboxing the unit and powering it on. So I suppose that qualifies as “turned off” before the upgrade?
App version 1.1.1 (109)
Front panel version 1.10
Control board version 1.10
Network board version 1.1.1 (504)
Similar to the photo at the top of this thread. Thanks again.

Thanks Andre. If you took it out of the box , then switched it on checked Mosaic and selected the update then it would have been running v.1.1.0 at that point. Most ( if fact nearly all) of the problems encountered with v1.1.1 updates have been caused by the switch off and wait before requesting the update sequence of events. Your sequence is unusual doing the it straight out of the box .

So I am speculating that you have either a corrupt installation of either v.1.1.1 on the DAC or the app or both. The app is easy to rectify simply by downloading a fresh copy from App Store or Google Play Store depending on your platform. If this does not fix the issue ( after a hard reboot of the DAC) you may need to reinstall v.1.1.1 on the DAC. Please see the later postings in this thread on how to do it:

Bartok's streamer freeze with new expanse mode

I think it goes like this: First retrieve the device logfiles, so you can communicate them with dCS: Then you can do a factory reset of the device. A reset of the device option is available on the same screen as the log file download, see link above. Delete Mosaic app on iOS or Android device. Reinstall Mosaic app, and do a 1.1.1 firmware update as described above.

The other information that could assist in tracing the cause of the problem is the programme source . Is it happening with UPnP files, streaming services or everything? What UPnP server software are you running?

EDIT: Since writing the above I have been looking into the effect of using a factory reset. Unfortunately that will not return the software version currently installed to that installed at the factory. It just returns the configuration settings to factory default.

Hopefully James of dCS will pick up on this and be able to advise further.

Thanks much Pete for your reply, and the edit. Yes, once you upgraded the firmware, a factory reset doesn’t reverse that. I’ve now (1) re-installed the iOS Mosaic app, (2) done a Bartok factory reset (twice actually) and will now monitor if the issue comes back or not. It happened previously with basic streaming of Tidal (network source).

I hope the Mosaic app could add a function to shuffle the tracks in the entire library.

I have been experimenting with Expanse on my Bartok HDAC. Here is another great reference track for showing how great Expanse is. Expanse 1 sounds much better for headphone listening.

Just got my dCS remote and mute isn’t working - tried quick and slow presses of the mute button on the remote and nada, nothing, though I can hear a clicking on the Bartok unit.

Tbh the mute button on the Bartok itself is hit and miss anyway, but the whole point of getting the remote was to be able to control volume AND mute from the sofa.

There’s little point in having a remote and still getting up!

Hi all,

A note on our next steps following the Mosaic 1.1.1 release. We appreciate that some of our users are not as delighted with the latest version of Mosaic as we had hoped, and are truly sorry for those inconvenienced by some of the unintended side effects that have popped up. I think it is worth explaining the long incubation period of this release; not only has the COVID-19 pandemic forced our design teams to be dispersed throughout the year, but there have been quite major changes required on the back end to continue supporting the streaming services currently supported by Mosaic (which is for example why you had you re-enter your TIDAL credentials after the update).

Additionally, the extra features (most notably Expanse) we have added have required substantial research, development, listening and testing – remember that Expanse works at all sample rates and formats without compromise. In our haste to provide these features in time for Christmas, unfortunately we couldn’t roll in all the features and fixes that we wanted to (we are only human!).

On a positive note, we now have put in all that effort, so we can now concentrate on a much quicker release of the next version of Mosaic. I should note that it will be a fix based update not a feature based update, aiming to get the features currently available working as they should be. Thank you for your patience and feedback on the release, and watch this space!

@James Still watching this space
