Converting analogue source to digital stream on the fly

I have an old Thorens turntable connected to an Arcam amplifier and I would like to be able to convert the output to digital so that it could be recorded and/or streamed, ideally, say, by MinimStreamer running on a RaspberryPi. The idea solution would be an A/D card for the Pi, similar to the Hifiberry DAC, but no such product exists and the people behind the Hifiberry card say there isn't sufficient demand to merit producing such a thing, which would be challenging anyway. I thought I had a relatively low cost solution in the Roland UA-55 Quad-Capture Audio Interface, but it turns out it uses a proprietary software that is only Windows or Mac compatible. Can anyone recommend something of similar specs that would be Linux compatible?

The Wolfson (now Cirrus Logic) audio card for the Raspberry Pi does this. I have used it for playback but not for recording. The hardware is good but I haven't been impressed by the usability of the software. For example, you need to use a Wolfson/Cirrus custom version of Raspbian because Wolfson/Cirrus hasn't yet integrated the drivers into the main Raspbian build.
