I think this suggests some problem between my SB Touch and TIDAL.

Re: [SlimDevices: Touch] Streaming Tidal to Squeezebox touch
Thanks so much Michael. One clarification: When I first used the new MySB Tidal app, I noticed the "Streaming Quality" selection and set it for FLAC or MP3. As a premium TIDAL user, is FLAC quality streaming without any further setting adjustments to my SB Touch units? Our implementation defaults to the best quality available to the user. -- Michael ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Streaming Tidal to Squeezebox touch
Ok, what's the story behind Logitech's freeing up resources to build the TIDAL app at MySqueezebox.com? I figured this was a dead issue. It's Logitech's commitment to keep the Squeezebox/SmartRadio alive for existing users. Part of this is updating the code when needed. A few months ago I was contacted by WiMP/Tidal as well as Spotify people about their intent to shut down existing systems we were still using. In order to keep our implementations alive we had to make some steps forward. If already we had to move on to the new Tidal API to keep existing WiMP users happy, we could as well launch Tidal for all customers. on my MacBook Pro. My TIDAL libraries via looking through TIDAL's apps are complete. But when I access using the iPeng app (via LMS on two different computer OR via Logitech's server platform they are incomplete. Why? If this is a problem you're only seeing on iPeng, then you might want to get in touch with pippin. He might be able to give you and me some background information about why this might be failing. -- Michael ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Streaming Tidal to Squeezebox touch
Ok, what's the story behind Logitech's freeing up resources to build the TIDAL app at MySqueezebox.com? I figured this was a dead issue. :confused: So, here's my reoccurring problem which I thought should have resolved when I connected to TIDAL via MySqueezebox.com or via LMS 7.8.1 running on my MacBook Pro. My TIDAL libraries via looking through TIDAL's apps are complete. But when I access using the iPeng app (via LMS on two different computer OR via Logitech's server platform they are incomplete. Why? I did recently install a new DSL router. Could the router be blocking some communication? *Source*: Streaming TIDAL, Pandora, other > Logitech Media Server 7.8.0-ickStream plugin, with iPeng app on iPhone6s/iPad *Great Room*: SB Touch(1) > AudioQuest Toslink > PSAudio DL3 DAC > Audio Envy interconnect 10' cables > 200w powered Martin Logan Purity speakers, SB Touch(2) >JVC 110w amp > Martin Logan Motion 4 & AudioEngine 5. *Garage:* SB Touch(3) > Wyred mINT > Cullen Cables > Martin Logan Motion 12 *Carry Anywhere: *TIDAL and Pandora >iPhone 6s > Bose Mini Bluetooth speaker.
