I'm on the latest firmware. Is this fixable? I really like the receiver and features, but I can't deal with this issue.
What are the details of this sleep bug?
Your comment " .. I pulled the plug and voila, it began working again." suggests you resolved this?
I did a Google Search on 'Onkyo sleep bug' and the immediate results are to various Onyko firmware updates for TX-NR708 / TX-NR1007 / PR-SC5507 units,
I can't see the word sleep in the firmware fix summaries but the most comment item reads
Stabilizes operation immediately after power is turned on (thereby avoiding problems of no sound output after the A/V receiver has been in Standby mode for an extended time with network control enabled);
This suggests this might be an old issue and was fixed on older Onkyo units by firmware updates, although if that's the case then it's disappointing to see it reappear on new models.
Of course I'm really speculating here given I don't know what the 'Onkyo sleep bug' is
