@Cantodea @jcn3 Hi guys. I’ve finally had a chance to give mine a try, haven’t been able to replicate, tried on a couple of networks too. Had a quick chat with customer service.
I’m assuming you are both up to the latest firmware? Last one released was Nov-2019. If not, first port of call is getting that firmware updated.
If you have, and/or have now done and still seeing the issue - open up the KEF Control app, turn on the LS50W, make sure the speaker is ‘connected’ in the app and then replicate the issue in Roon. Don’t power cycle LS50W until the next steps are complete.
Once replicated, pop into the settings section of KEF Control - at the bottom you’ll see ‘Send Logs and Feedback.’ Your email browser will pop up, and you’ll see an email already populated with a bunch of info, and the speaker logs will be attached (Cycling power will reset these logs, hence the previous mention of not power cycling). If you could write in a bit of description of what you are observing (does it happen on all music sources i.e. locally stored music, Tidal etc, is there an error message anywhere - anything you can think of) that would be really useful. Be as descriptive as possible (maybe not to Tolkien levels of 'talking about a tree for 7 pages though…). This will send a whole bunch of info directly to the dev team, who are much, MUCH better equipped and knowledgable at looking at code etc than I ever will be.
