Hi,

 

I dont mean to necro but the fix works! Thanks for that, i already give up my e7 for the same problem right channel dead when used as dac. Thanks for finding this solution.

Wow this worked. You are awesome my friend. Anyone know why this works?

As a dude with same problems, JUST after buying it used, without receipt, I was worried. I tried plugging the jack into aux and back, and it worked! Thanks for that mysterious, but obviously fool-proof fix!

If I wiggle a jack in the aux in while its a DAC, sound comes briefly... god dammit this is so infuriating. Really what the heck.

Thanks - the fix works for me too. Not quite sure why it worked, but it did!

 

It did not quite work immediately, but I did some wiggling around on the Aux input jack. After a few tries, both output lines just (magically) work.

Ended up giving up and selling my E7 as a portable amp to a friend. I'm pretty sure it's something to do with the DAC

Pretty sure it is just the jack.

Considering the aux in worked perfectly 100% of the time, it had to be the DAC that was causing the loss in channel.

The AUX-in actually also double as a mechanical switch to activate / deactivate the feeding of DAC signal into the amp section, it is a way on how the E7 'priolitize' which signal gets to the amp section over which when there is more than one input (such as having E7 connected to a PC while also have the AUX-in plugged in). The fact that you get a briefly working DAC when the jack in plugged in is a good sign that indicates the DAC section is working just fine, but the plug itself which uses a mechanical movement (where the 3.5mm plug physical plugged in) to switch between signal is very likely broken. If it is a DAC problem, it won't have worked at all. The plug / switch mechanical thingy is know to fail / loosen in time, making it less sensitive therefore the feeding of DAC signal keeps getting disabled or interrupted. You will know when plugging in the AUX-in temporary fixed the issue, as it physically force the plug to do a switch. Most of the time it will be fine afterward, at least for awhile. But in your case, the plug might be a bit too perished so the problem remains even after plugging-in/-out the AUX-in.
