Hello,
I received the "Digi" version of the Hifiberry a few weeks ago, but until then I did not have time to try it.
I soldered the pins to the raspberry, plugged the digi onto the Blackberry, checked the soldering, checked the "green ligh" on the digiberry, loaded the modules and ran various tests.
Sadly, it does not work....
The symptoms are quite strange, each time "aplay test-sound.wav" is played on the raspberry, without changing any other parameter (loop "aplay, ^C, aplay, ^C, aplay, ^C...") the output is different:
- sound level is unpredictable, from "I cannot hear anything" to "the headphones will explode in 5 4 3..."
- sous quality is unpredictable, from "very nice" to "schkrkrkkrkschtttt"
I insist: the physical and logical setup is unchanged between 2 tests.
The "test SD image" presents the same symptoms.
The "test sound script" presents the same symptoms.
I tested plugging the Digi on 2 different DACS. Same thing.
Is it a faulty DigiBerry ? I checked the soldering and it seems fine.
Best regards,
Amaury

HiFiBerry team Dear Amaury,
this is a very strange problem. Working/not working might be a hardware problem, the the sound level can't be changed as the card passes the software.
Are you using the optical or electrical output. If electrical is it a card with or without the transformer? What DAC are you using?
Best regards

Amaury Doe Hello,
I am using the optical (toslink) output.
1 have 2 DACs: 1 Cambridge audio Dacmagic 100 and an Advance Acoustics MDX-600.
Same issues appears for both DACs.
Problem is reproductible with test sound file or a standard WAV file.
I tried 2 pair of headphones, in case it was defective. Problem persists.
From my point of view the hardware is faulty.
I will triple check the soldering to make sure the issue does not come from there.
The green led on the Digi is steady.
Best regards,

HiFiBerry team Dear Amaury,
we have to check the device here. Please send it back to us including your order number. We will test and replace it.

Amaury Doe Hello,
I redid the solderings yesterday, just in case: behaviour stays the same (AKA erratic), for example just pausing aplay (^Z then "bg" for example) will change the sound setting and display the aforementioned random sound quality.
The only component that I was not able to duplicate was the RPÏ itself as the DigiBerry connector is soldered on it.
I will send you the (likely) defective board.
Best regards,
Amaury
