Hey @Tamir_Dotan,
Thanks for confirming the firmware, and for sticking with this. I want to step back, because your testing has actually cleared a lot of ground, it’s not Tidal or your internet (the track was always fully buffered server-side), it’s not the Arcam (zero dropouts across every event), it’s not DNS, and the Wi-Fi test cleared the Silent Angel switch. Solo playback has never dropped either.
What’s left is very specific: it only happens when both Bluesound units are in the group and the stream is high-resolution, and they drop together. That’s a grouped-sync-under-load pattern, so I’d like to test the two variables we haven’t cleanly isolated yet. In order:
- Disable Sample Rate Conversion on every zone in the group, including the Arcam. A grouped zone plays the highest common stream, so with the Arcam still upsampling to 24/192, your network is likely still carrying 24/192 to the Bluesound units even though you disabled it on them. Turn off all upsampling/DSP everywhere, group them, and play. If this holds, we've found both the cause and a workaround.
- Remove the 100ms zone grouping delay you set on the two Bluesound devices (set it back to 0), then test the group again. It directly affects grouped playback timing, and we've never tested with it reverted.
- If it still drops, group only the two Bluesound units together (no Arcam), DSP off, that tells us whether the two BluOS devices staying in sync with each other is the trigger.
