RME 9632

RME 9632

[Remy Bruno]

Hello,

I'm having a strange problem with an RME HDSP 9632 card I recently bought. I've
contacted RME, but would like to know if somebody here is having the same
problem, or if there is a known issue about this (and if possible, a
workaround).

Start of the story: a couple of monthes ago (let's say about one year, but I'm
not sure of the time-scale), I got a RME HDSP 9632. Alsa driver was working
perfectly, I got the 12 I/O (16 with the additionnal add-on cards), the mixer
matrix worked as expected (mixer params = src,dest,32768 with src=dest+16 for
sending playback channels to audio outputs). After an hardware problem with the
card (I plugged the analog add-on card while it was running, which burned the
card!), I had to get a new one. I didn't manage to get this new card work, so I
suspected a specific problem with this new card. More recently (one week ago),
I needed to use an RME9632, so I got a new one, and I'm having about the same
problem than with the 2nd one:
- card does not work in master. Everything is as if it ran at 24kHz (sound
  plays slowly), even if the card pretends to run at the desired sample rate
  (say 44.1 or 48kHz). So master mode is unusable.
  Master worked with the 1st card.
- in slave, it seems to be more or less OK, but the matrix behavior is
  extremely weird. For sending playback channels 9,10,11,12 on outputs
  9,10,11,12 (SPDIF & analog), I need to put the value 32768 in the following
  coefficients: (62, 4), (1, 6), (24, 6), (15, 7)
  With the first (now dead) card, I used the normal following matrix
  coefficients: (24,8) (25,9), (26, 10), (27, 11)

Any idea?

Thanks

Remy

I'm not quite sure (only started working on this), but your problem
might be a firmware incompatibility. If so, it might help to downgrade
(using http://rme-audio.com/download/treiber_archiv/fut_win_dsp.zip ).
Could you supply your output from lspci?

Hi,

Thanks for the link. I'll try to find a windows machine to do the downgrade.

Indeed, the card I have is revision 152:

Bus  4, device   8, function  0:
    Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev 152).
      IRQ 11.
      Master Capable.  Latency=255.  
      Non-prefetchable 32 bit memory at 0xfaaf0000 [0xfaafffff].

Regards,

Remy

OK, I downgraded the firmware and it works now perfectly!
Thanks a lot!

So to summarize:
HDSP9632 with rev <= 151 works OK with current alsa drivers
HDSP9632 with rev >= 152 doesn't work with current alsa drivers

Regards
Remy

PS: I just received an email from RME, maybe it will allow to modify the alsa
driver to support rev >= 152, but the simplest for now is to downgrade the
firmware.
