[Blackstone]

I’ve seen this type of thing before. Reflash with the latest firmware. What version are you running? The reflash will get your sound back, I’d bet money on it. Then if it happens again unit needs to go back to Ayre, probably.

Release Notes:
This firmware is designed only for the Ayre QX-5. Compared to the previous official release of firmware revision F, this version corrects a bug with sample rate timing changes and clock mode selection. It also updates the network naming for the unit.
Bug Corrections:
Created a sample rate timing change to avoid issues with DSD/PCM switching and drop-outs on some units.
Corrected a critical bug that caused the clock mode to behave incorrectly. This caused issues with MUSIC mode of all S/PDIF inputs to output lower quality sound than expected as well as prevented VIDEO mode from syncing correctly.
Improvements:
Updated the model name on the network list to help identify it on the network with new products.

Known Issues:
An issue was recently discovered that can cause short drop-outs in audio while playing DSD files over the network. When the DSD flag is brieftly lost, this will sound like brief pops or drops in output. The correction for this bug will be implemented in rev. H.


Firmware Updates:
Firmware updates may be made available for the QX-5 Twenty. These updates may provide new features and/or improve the use and reliability of your unit. There are two types of firmware updates that are available for the QX-5 Twenty.

Do not turn off the QX-5 Twenty while updates are in progress.
