USB Revolution DAC No more sound

[LucasAllo]

Dear Support Team,

 

I am using the Allo USBBridge signature (Volumio) + Allo Revolution DAC.

It was really a nice setup with a sound quality, above than expected, with a lot of natural and pleasure to listen without auditive fatigue, thanks for that.

Unfortunatelly I have an issue which seems coming from the DAC, I can't get any sound output.

The DAC is still recognized by volumio, and display is responsive to inputs, but I have no sound. When I reinstall everything, I got 1 or 2 sec sound, and nothing after. Sometimes, I have an error explaining output is no more available, and rev DAC is no more visible as USB output.

I had some issue with the USB cable (yours as well), which seems to be defective, so I changed it -> No change same behaviour.

I tried another DAC with the USB bridge: no issue.

I tried the rev DAC with a windows computer: it works.

I have followed the procedure to update DAC USB drivers: no changes.

I raised a ticket to volumio, we did not yet find any issue on that side, I have a phone call tonight.

 

Now I am totally stuck and really need your support.

Thanks in advance.

I forgott to add. 

I have a strange behaviour using the DAC with widows computer:

After 1 hour of use I got a BIP every minutes !

The BIP is arrounf half a second, and replace the ongoing music. 

I discover this yesterday, and issue is reproductible, just need 1 hour, and after you got it every minutes (very precise).

 

Hope it helps !

Dear Allo team,

 

I can't understand why I get no answer since you received my unit.

 

Your support was reactive and appreciated, but since more than 3 weeks I got no feedback at all.

 

Please anser and provide visibility, I start loosing confidence in your company.

 

Regards,
