Digital IO Optical Out No Audio
Hi all,
I've recently bought one of those cheap DACs with optical input and two RCA jacks in the output, and I'm not getting any sound from the Mister (I do get analog sound just fine).
I tested the DAC with my TV set, and it works as expected. On the Mister I can see the red led that goes into the jack and it's on and I also looked for the 96khz setting on the ini file, and it's 0. What other things can I try ?
Are the DIP switches on the DE10-Nano set correctly?
For digital IO they should be set to:
SW0 | SW1 | SW2 | SW3
OFF | OFF | OFF | ON
Most common issue is cable not good enough. Second problem seems to be wrong kind of led on i/o board.
My optical audio out stopped working overnight. Just as that, one day worked, next day didn´t. The cable runs fine with another optical setup so does the DAC. I´ve been thinking a while about buying a new cable but I fear the very same result.

Check resistors R3 for 200 ohms and R4 for 1000 ohms with a multimeter. I've seen misteraddons resolve it for someone by having them replace a resistor that went bad. Other times replacing the LED will be required if the red LED isn't working anymore.
Hi all,
I finally was able to see how the dip switches were positioned and I had SW0 ON and SW3 OFF like so
SW0 | SW1 | SW2 | SW3
ON | OFF | OFF | OFF
But, when I tried to move the switches like so,
SW0 | SW1 | SW2 | SW3
OFF | OFF | OFF | ON
I've no longer had VGA (since I'm using a CRT TV) nor audio.. I'm really at loss here.
Hey guys,
I've just noticed something that might be an interesting observations: when I connect the DAC dongle, the USB red led that goes on whenever I plug other devices, stays off. Does that mean that maybe my Mister is not pulling enough current to be able to power on the DAC properly (eventhough its power on led goes on) ?
