Hi James, I tried without alsaconf and that fell flat on its face - I could see that the usb device had been detected but I was unable to record without the software either (a) simply not working, or (b) getting in a right state, necessitating a reboot of the machine to clear. I suspect some if not much of this is down to the peculiarities of running Puppy from a usb stick - nothing wrong with that as a rule but it may be a bit 'specialised' for this particular application. Even with the alsaconf workaround the problem appears to be that alsamixer (or any other mixer for that matter) only shows a playback slider for this device in the 'playback' and 'all' views; the capture view is completely blank. This seems a little odd to me given that the primary, if not sole, purpose of the device is channelling the output from the phono stage to a digital recorder of some description, i.e. I could get my head around the opposite scenario. So, my options seem limited to: (1) contacting Pro-ject for advice. (2) taking the output from the phono stage and channelling that through the line-in socket. (3) exploring the option of using my Rockboxed iAudio X5 to capture the output somehow. Since both 2 and 3 effectively waste the additional £75 I spent on the phono stage over its non-usb counterpart (which cost me a tenner from a mate), I'll start with 1 and work down the list!
