Hello everyone,
to have another digital audio i/o card for our studio / office, I got a pair of RME32 the other week from ebay. (mostly as reference to implement ADAT for the RAD1 Sgi/Octane ALSA driver, …)
Unfortunately they do not work with Linux. They are recognised and all the usual devices and /proc/… entries show up, however, the hardware pointer does not move during playback or capture no matter what clock source I choose.
I tried attaching coax s/pdif as well as an 8-channel Behringer Ultragain ADAT source w/ clock.
The two cards came from the same seller, look ok and both behave the same.
I went so far to install a Windows XP test install where both cards work “more”.
(They are not perfect in windows, however, at least s/pdif can come out with or with-out external ADAT clock source. However, the digital signal strangely unclean, but that may be a bug in the window system sound device emulation, I only tested with foobar2k and not some Pro audio app which I do not really have).
Long story short, does someone still have such a card, or not moving hardware ptr (or missing interrupts?) does ring a bell regarding this RME generation? Instead of a working ADAT reference card, I apparently have two ALSA driver to hack on, … ;-)
I tested two different “PC” boards and the results were the same, too.
Thanks,
René
