After a few tracks playing consistently on my STi7 (with HQPe 4.9.0 enabled and upsampling with intermediate filters to DSD512), playback suddenly stops (no crackles, stutters or signs of CPU stress) and it’s very difficult to recover the system.
At first, I hit Play and the playback chain light appears showing a correct config, but the timeline indicator freezes (but can be moved to any point in the track and just freezes there instead).
Then, after rebooting the microrendu and then the STi7 (or vice versa), a further attempt at playback results in the message “Playback failed because $ couldn’t connect to HQPlayer”. So, a look at HQPlayer Config to ‘re-Apply’ is attempted only for the same failure message to appear.
Ultimately, I have found that a hard reboot of the STi7 and/or the microrendu can eventually result in a need to log back into HQPlayer Config such that two options become available under ‘Current’ instead of one. This signals the point that I can recover playback by making an output device selection under ‘Current’ before returning to Roon to hit Play again with success.
But playback only lasts a few tracks before the whole saga returns.
Both Core and Remote are 1.6 (build 416), the network is stable confirmed by the fact that internet radio on my Naim Uniti is rock steady (it uses the same switch as the STi7) and all connections have been confirmed to be solid.
What can cause this frustrating instability and has anyone else encountered similar behaviour and fixed the issue? Thanks.
Note: Playback ‘front end’ chain as follows…
STi7 (SW 2.7, HQPe 4.9.0) fed by HD Plex LPSU (Netgear GS105 switch)
Direct link from STi7 to microrendu v1.4 (SW 2.7)
USPCB connection from microrendu (LPS-1 powered) to modded Singxer SU-1 (LPS-1 powered).
I2s connection from SU-1 to Holo Audio Spring Level 1 DAC.
Network involves a TP-Link 100CM FMC at the router end and the same at the other (receive) end of 8 metres of SC-SC cable. The FMCs are powered by ifi Audio iPSUs at 9V. The receive end FMC then connects to the Netgear switch via a short run of UTP cable.
