Re: hdsp driver and tools update

[Roslyn Hoskin <roslyn.hoskin@nautronix.com.au>]

Hello all,

I'm a friend of Nick Arnold who has previously posted to the alsa -devel 
regarding problems with the hdsp9652 card. I am using the same system as 
him.

Whereby we are running

RME Hammerfall HDSP 9652 card working

> with ALSA 0.9.8 on a SMP redhat 9 box.  We're trying to use 12 input
> channels and three output channels, running at 48Khz 


We are interleaving our the channels in our code to run at 96kHz. we are 
syncing against an external word clock. and the system clock needs to be 
set as a slave

I'm trying to get the card to run at 96 kHz with the sample sync source  
(using the 0.9.8 driver and thomas patches and hdpsconf and hdspmixer).

When i change to autosync running @ 96kHz the system source clock 
changes to master and the card will not open.
below is the error I get?

.ALSA lib pcm_hw.c:324:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS 
failed: Operation not permitted
ACCESS:  MMAP_NONINTERLEAVED
FORMAT:  S32_LE
SUBFORMAT:  STD
SAMPLE_BITS: 32
FRAME_BITS: 448
CHANNELS: 14
RATE: NONE
PERIOD_TIME: (85333 85334)
PERIOD_SIZE: 8192
PERIOD_BYTES: 458752
PERIODS: 2
BUFFER_TIME: (170666 170667)
BUFFER_SIZE: 16384
BUFFER_BYTES: 917504
TICK_TIME: 10000

When I changed to autosync @ 96 kHz the hdspmixer shows 26 input 
channels and not 14?

When I change to internal 96kHz the hdspmixer shows 14 channels but the 
sync check on ADAT1 In, ADAT2 In, ADAT3 IN and WordClock change from 
Sync to lock and vice versa constanty.

Any Help on this would be great??

Thomas the hdspconf looks great, much easier to use than amixer!!! 
Thankyou and thanks also for the Patches!!
