The studio computer has an RME 9632 and a stock sound card. It is
mainly running Arch (latest Alsa and no problems), but I experiment with
other systems all the time. The Debian system (laptop) has just a
stock soundcard as well and running with relatively older (1.0.23) Alsa
support and has no problems. Sometimes I will test things out between
the two with the Audiobox (usb). Interestingly, with a 'standard'
Ubuntu 12.04 (although 32 bit and not 64 bit as is Ubuntu Studio) I did
not have this problem...so 24 bit files were playable after I compiled
Alsa-Tools.
