I use a USB Signature, and had a problem with volume control on a Douk u4 Dac, in order to fix this a friend of mine loaded Moode and was able to open up a SSH and use alsamixer to return the volume control to 100% as it had dropped to 50%. When returning to normal play on Ropiee the change remained. Now when we played the moode software as an end point (I play off a Audirvana on a MacBook 4 switches away) we could have just continued to use moode, AND have the ease of returning the volume if it ever tripped back to 50% in the future. BUT it kind of clearly did not sound as good, so we switched back to Ropiee. Rich

I am using a USB Dac and streaming with Ropiee, but I wondered if I could also play my CDs using a transport or CD player with digital out somehow into the Allo USBridge and into my USB Dac?

Hey anyone understand USB volume negotiation? I have 2 near identical DACs - Douk u4, one is an early example with a Phillips DAC chip, and the other is a later version with a BirrBrown Chip. I use an ALLO USBridge signature to play as an endpoint using Ropiee from a macbook playing audirvana. The douk uses a PCM2704 chip for the USB duties (but not the DAC). On my old unit it plays consistently at full volume, on the new Bur Brown units it suddenly negotiates to a really quiet volume and can't seem to be reset back. This is only using the Allo bridge and Ropiee as if I send USB direct to the new Burr Brown Douk then normal volume returns, but only when played direct from the MBook. Any ideas it's driving me crazy!!! Thanks, Rich

Hi, I am creating my own cable to supply the USBridge Signature with 5V power. Can you let me know out of the possible connections for 5VBUS and GND which ones operate in the USBridge to make sure I connect the cable correctly. Thanks, Rich

Hi - I used a cheap current meter in series with the supply and measured peaks of just 1.3A for a very short period and a steady state of about 500mA could that be correct. I am using Ropieee software on the USBridge Thanks

Thanks for the reply. I will be purchasing a Shanti soon, but wanted to be clear on what I need in the interim Rich

I am really pleased that your products will become available again. I am currently using a USBridge Signature, and wanted to understand what the Power Supply requirements are if this is available information? Specifically what is the operational mA whilst in use. I only use if with a USB DAC, and Ether net port, using Audirvana on a MacBook to supply the music to the bridge which is running RoPiee Thanks Rich
