192khz working for anyone? and RME96 patch broke

192khz working for anyone? and RME96 patch broke

[Daniel Pouzzner]

First the RME thing: Torger's post-RC6 patch to rme96.c broke
double-speed capture, so that there is nasty clipping/Nyquist-type
garbage in it.  This is definitely in the patch itself - a CVS kernel
with an RC6 rme96.c works fine.

--

Now for the main attraction.

I'm looking for any way to get 192khz audio working.  If anyone's
gotten it working (under ALSA), I wanna hear how.

I tried Audigy 2 with no success.  opensource.creative.com now has an
Audigy 2 linux driver available, but I don't want to go back to that
card, and I don't want to use a non-ALSA driver.  Consumer cards are
just painful, and Audigy 2 has no 192khz capture hardware, in any
case.

My next try is the Envy24HT-based (ICE1724) ESI Waveterminal 192X.
This is a pro card, much more appropriate for my purposes.  It has
192khz capture and playback.  The CVS ALSA kernel purports to have
basic suppiort for ICE1724 now, but it's not working for me:


  Bus  0, device  14, function  0:
    Multimedia audio controller: PCI device 1412:1724 (IC Ensemble Inc) (rev 1).
      IRQ 9.
      Master Capable.  Latency=64.  
      I/O at 0xef40 [0xef5f].
      I/O at 0xec00 [0xec7f].


but then


modprobe snd-ice1712
/lib/modules/2.4.18-xfs/kernel/sound/pci/ice1712/snd-ice1712.o: init_module: No such device


Any ideas?  The vendor and device IDs match the 1724 stuff in
ice1712.c, and not being an ALSA or Linux kernel savant, I don't have
an intuition where to go from here.


I'm perfectly willing to send this card back and try another, if
anyone has gotten 192khz ALSA working on it.

Strange, I did not touch that code specifically. Anyway, so you have 
tested with an old ALSA and the new driver (rme96.c) and that does not 
work?

Is it double speed capture from analog, or from digital input you are 
having problems with?

oss (and ALSA) drivers support audigy2 (and audigy1) only partially as
emu10k1 compatible. that is, the maximal rate is up to 48k, anyway.
btw, audigy2 is also supported by ALSA cvs (secretly, untested :)

what is the kernel message?

but, i don't think the card will be working immediately because
usually you need to write codes for ADC/DAC on the card.


ciao,

Yuppers.  Pinned it down pretty carefully.

Analog.  Haven't tested digital for the bug yet.

Ah ha.

  ALSA ../../alsa-kernel/pci/ice1712/ice1712.c:2472: invalid EEPROM version 120

the driver wants version 1 and barfs on anything else.

If I disable the error-out at that point in the code, here's what
results:

  ALSA ../../alsa-kernel/pci/ice1712/ice1712.c:2472: invalid EEPROM version 120
  ALSA ../../alsa-kernel/pci/ac97/ac97_codec.c:1829: AC'97 0:0 does not respond - RESET [REC_GAIN = 0xffff]
  ice1712: cannot initialize pro ac97, skipped
  devfs_register(unknown): could not append to parent, err: -17
  devfs_register(unknown): could not append to parent, err: -17
  devfs_register(unknown): could not append to parent, err: -17

The module then deals with the card well enough for it to come up in
amixer with read/write access, but not well enough to actually make
sounds.  Only S32_LE is accepted at all, the others producing "aplay:
set_params:1346: Sample format non available".  If S32_LE is used,
aplay and record block for a few seconds, then product

  aplay: pcm_write:1623: write error: Input/output error

or

  arecord: pcm_read:1710: read error: Input/output error


Other glitches:

  douzzer@triceps douzzer $ /usr/sbin/alsactl -f /tmp/bla store 2
  /usr/sbin/alsactl: get_controls:484: snd_ctl_open error: No such device


Clearly more work is needed in the driver.  I'm sure I'm missing some
vital details on the card needed to do it, not to mention, some vital
skills (I'm a hacker of neither the linux kernel nor the ALSA
kernel).
