Philips Hearlink first Impressions

I think I tried to warn you in the other thread Oticon OPN 1 and TV Streamer - #33 by Volusiano the following:

@Volusiano

One little quirk about the Oticon TV Adapter that I ought to mention to you, though, is that if the analog audio level coming into it is low enough (below a predetermined threshold), it may still work fine, but after so many minutes, it will go into stand-by because it assumes that there’s no audio activity at the input. So you will need to set it at a volume level high enough to keep it detecting above-threshold audio to keep operating. But since your already have your Genie 2 program turned down to -9 dB, you should be able to set the audio in to the TV Adapter hot enough to keep it from going into stand-by.

I suspect that this is what you’re experiencing. You analog audio in to the TV Adapter from your DAC is set too low, below a threshold level that the TV Adapter deems to have an active analog audio going on. So after several minutes, the TV Adapter will go into standby to save energy. By recycling the DAC’s power supply, you probably started an initial large enough spike that wakes up the TV Adapter from standby again.

So the trick is to find a hot enough level of input from the analog audio going into the TV Adapter from the DAC that will keep the TV Adapter from going into standby and continue to be awake, but not too hot like the Toslink that would blow your ear drums off. I don’t know what this hot analog level needs to be, but hopefully by experimenting with it, you’ll find a working hot enough level and it’d still be acceptable to you and not too hot like your Toslink level.
