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.
Does the /proc/asound/card*/rme32 entry show the right setup? RME32 seems to have only few registers, and it behaves differently for read and write. Maybe you should try to watch the register 0x20000. The hwptr is the LSB 33 bits.

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

Replace the copy and the silence ops with the new merged ops. The conversion is straightforward with standard helper functions.
