Hello again,
We seem to have got the card working both for capture and playback(!).
Thanks to everyone for their replies. We were not expecting so much positive
response. If any of the respondants are in Fremantle Perth sometime send us
an email and we'll take you to lunch!
The three things we did:
1) applied the patch to the hdsp driver. This solved (rather than
"ameliorated" as I incorrectly wrote earlier) the unexplained signal on the
output channels.
2) found the right "amixer" settings for our setup:
#!/bin/bash
amixer -c 0 cset numid=11 0
amixer -c 0 cset numid=13 0
for i in $(seq 1 26);do
amixer -c 0 cset name=Chn,index=$i 32768
done
- ie. the sync reference was an external word clock, so the card should
not use any internal clock source; and output channels should be turned
on.
(I neglected to mention earlier that we have an external work clock source
and hence the card must run as a slave and not use any of the "Internal
XXX kHz" sample source clock settings. It took me awhile to realise the
importance of this piece of information.)
3) changed to a working AD/DA converter box. :) Almost at the point of
giving-up we swapped to a different AD/DA converter box and found the card
worked!
I've attached the output of "amixer contents" and the interesting bit of the
output of "lspci -vv" for the curious. You'll notice the card is presenting
as having 26 channels. This has meant we have needed no changes to our
software from the "old" Hammerfall.
Our software was originally written to work with the "old" Hammerfall -- I
believe now called the DIGI 9652. To the best of our understanding that card
had no knowledge of ADAT "double speed" and hence we opened the card
requesting 48kHz sampling and 26 channels. We did the (de-)interleaving of
channels ourselves. This was done because we were under the impression it
would support no other setttings.
Now this software is running without change with the new card -- ie. 26
channels; 48kHz; and we're doing the (de-)interleaving. This is a great
result.
If this card is capable of performing the channel (de-)interleaving for us
under our setup (a slave device auto-syncing to the word clock) we'll
probably start looking into getting this working sometime soon, but its a
lower priority.
Anyway, thanks everyone for your help,
nick.
