[alsa-devel] Issues with HDSPM

[Andre Schramm]

Hello,

the HDSPM driver seems to be broken in the current ALSA release.
We're using CentOS 5 with 2.6.33.9-rt31.64.el5rt and ALSA 1.0.24
compiled from source, the card is a PCIe Hammerfall DSP MADI (rev d2).
As already mentioned in [1], the card operates in master mode, but the
system clock mode can't be set to anything higher than 48kHz.

# amixer cget numid=3
numid=3,iface=MIXER,name='System Clock Mode'
  ; type=ENUMERATED,access=rw------,values=1,items=2
  ; Item #0 'Master'
  ; Item #1 'AutoSync'
  : values=0

# amixer cset numid=2 5
numid=2,iface=MIXER,name='Internal Clock'
  ; type=ENUMERATED,access=rw------,values=1,items=9
  ; Item #0 '32 kHz'
  ; Item #1 '44.1 kHz'
  ; Item #2 '48 kHz'
  ; Item #3 '64 kHz'
  ; Item #4 '88.2 kHz'
  ; Item #5 '96 kHz'
  ; Item #6 '128 kHz'
  ; Item #7 '176.4 kHz'
  ; Item #8 '192 kHz'
  : values=5

# amixer cget numid=6
numid=6,iface=MIXER,name='System Sample Rate'
  ; type=INTEGER,access=r-------,values=1,min=27000,max=207000,step=1
  : values=48000


When switching to a PCI version of the card, the kernel completely
crashes on boot.

And with [2], there is another issue which unfortunately hasn't been
merged yet and still exists in the current release.


Regards,
   Andre
