USB out - extremely low volume

[Robbyrtp]

I have tried to connect the very same way as you with exactly the same result, but when I removed the smsl po100 the volume was normal. It looks to me that the smsl needs more power, maybe from a usb hub.

I think you may be correct. Although, I believe I’ve heard of other people using PO 100 without having this issue. My next step is to try a DAC that has its own power inout.

I just experienced the same issue you are having. I think there is a bug when setting the volume bypass.I had the volume set to 30 before activating it. I set the volume to 100 before activating the bypass and voila, volume is loud again

Interesting! I’ll have to give this a try. I sent the little DAC back assuming it was faulty. I’ll have to get another.

I was about to return a pair of fossi V3 monos because they sounded super low. I got them to play around with opamps and as a backup for my main amplifiers this black friday and I thought they were faulty. Then I realized the vu meter was only reaching about 25% although I had fixed volume output set to 100%. That made me scratch my head. So it seems it kind of “remembers” your last volume setting

Hi I plugged my WiiM Ultra into my DAC using usb and it was full volume, I wasn’t impressed with the sound though it was very sibilant.

So you need a better DAC now?

No I don’t think I need a better DAC than the ones I have already Denon inside the PMA1600 and a Douk Audio Q11 which I am very impressed with.
