I think I should start by explaining my understanding of drivers and dacs. All dacs need a driver so it can connect and work with the computer to which it is physically attached in order to play music. Windows, Mac and Linux all have standard built in drivers. If the standard driver does not work with a particular dac then a driver can be written for that particular operating system / dac combination. Most dacs on the market now work with the current Mac drivers. Very few dacs work with current Windows drivers but many dac makers provide a driver that will work. Many dacs work with the standard Linux drivers but I have not seen any dac maker provide a Linux driver when the dac needs one. Since the Squeezebox Touch is a Linux computer with standard drivers a dac will only play music with the USB input if it can work with the standard Linux drivers. Adding drivers to the server feeding the SBT will not help. Since your DAC2 plays music from the server with the coax input we can limit our driver discussion to the standard Linux drivers on the SBT. John Swenson said he thought Wyred4Sound uses the M2Tech OEM board which cannot use the standard Linux drivers and so their dacs will not work with the SBT. I asked Wyred4Sound if they use the M2Tech OEM board. The response was that the µDAC, mINT and DAC1 do not use the M2Tech OEM board. The answer did not list the DAC2. The DAC2 may very well use the M2Tech OEM board in which case it should not work in either async or adaptive mode on the USB input. Triode then suggested I as ask Wyred4Sound if the µDAC would work with standard drivers. The Wyred4Sound response was "The interface does work with Linux driverless in adaptive mode. It will not work with Linux in async mode." The µDAC does come with Windows driver which I have used to play music with J. River and MediaMonkey players. The drivers work fine but that has nothing to do with the SBT. Here is how I use the USB input on the µDAC: 1. use EDO, 2. connect the µDAC directly to the SBT (no USB hub), and 3. use the 9v external power supply. It automatically uses adaptive mode and plays quite well. As the µDAC has a 24/96 USB input I should have to use a USB hub with the EDO to get async. With a hub the SBT cannot see the µDAC. I suspect this means the the standard Linux driver in the SBT works in adaptive mode with the µDAC but does not work in async mode with the µDAC. I keep trying all of Triode's updates in hopes the async problem is really something else. If the DAC2 has the M2Tech OEM board you should not expect it to work with the SBT. I would do a test though by connecting the dac to the USB connector on the SBT and installing the EDO. If the SBT does not recognize the DAC2 you probably will not be able to get it to work. Not working with USB is not really a problem for you. The EDO gives you 24/192 playback on the DAC2 with the coax input. That should be great. I am using the EDO with coax on the µDAC and am quite happy with what I hear. The reason I am interested in the async USB input is that if it worked I just might prefer it to the coax input. This is not likely with the µDAC and its ESS Sabre chip but the tinkerer in me would like to know. Once Triode stops changing the EDO I expect I will just use coax input and forget about using the USB input on the µDAC. I bought the µDAC to use with MOG on the SBT and the total package is a delight.
