[linux-audio-user] USB Audio device with toslink spdif output

Hi, Can anybody recommend a usb audio device with toslink spdif output that works with alsa drivers? I need to add one to my pvr system as its onboard toslink is not well supported. My main criteria is price, and that the toslink optical spdif output must work reliably, I would really like to get a device that also has line-in connections which are output on the toslink, i.e. internally mixed into the toslnk output. I have found a few devices that might do the job: Audiotrak MAYA EX Behringer U-CONTROL UCA202 Voyetra Turtle Beach Audio Advantage Micro M-Audio Transit USB but it is hard to know if they are properly supported and work reliably. Any recommendation would be greatly appreciated. Thanks Andy
