Real-world reports on two Delta 1010LTs/ice1712 synched?

Real-world reports on two Delta 1010LTs/ice1712 synched?

[Petter Sundlöf]

Hello.

I have the chance to buy a second M-Audio Delta 1010LT (ice1712 chip) 
for approximately US$ 60. I've browsed through the mailing lists, and I 
couldn't find any definite practical/real-world results saying that 
synching two cards (via a BNC cable through the world clock connectors?) 
worked without problems.

Thankful for any hints.

Best,
Petter Sundlöf

Duane Holsbreck syncs two 1010 cards but he hasn't
been active on this list for a year or two. He's still
doing it.

There are a few things to be aware of. After it took me 2 months to get
two Delta 1010s working I put up a web page about it at

http://www.sound-man.co.uk/linuxaudio/ice1712multi.html

The info there might save you some trouble.
I'm using a (short) BNC cable made with a piece of TV co-ax to sync the
two boxes. It works. (OK the 1010 has the BNCs on the breakout box
instead of a flying lead like the 1010LT, but I don't expect that to
make a difference).
BTW the manual I got with my Delta 1010s says the word clock input will only
take up to 50kHz. I've been told by M-Audio tech support that this is a typo
and it will take the full 96kHz.

John,

Great page! This website was great news for me, and I immediately stuck
a 2nd delta into my machine today and went to it.

I upgraded to kernel 2.6.14, added the privided .asoundrc to my
/etc/asound.conf, applied the MMAP_COMPLEX patch to jack 100.7, applied
the pcm_multi-patch to alsa-lib 1.0.10 and applied the envy24 patch.

I am happy to say that seperate capture and playback of 16 tracks works
wonderfully.  I'm using spdif-out of card 0 to spdif-in of card 1 for
clocking at the moment, the recordings and playbacks sound perfect.  I
tested by playing 8 tracks (4 out of each card, all i had was 1 8-way
snake to test with atm) out of the delta's into a fostex G16 1/2" analog
reel, then played back out of the reel, again into 4 tracks of each card
and into ardour.  Everything seemed to be perfect, when running jack
with -C or -P.  I use -R for both the captures tests (recording into
ardour) and playback tests.

When trying to run duplex via: jackd -d alsa -C multi_capture -P
multi_playback (with or without -R), I get:

jackd watchdog: timeout - killing jackd
Aborted

And jackd dies.  I did nm /usr/lib/libasound.so|grep
snd_pcm_multi_link_fd to make sure that the patch applied correctly, and
nothing was returned, so all looks good there.  Does anyone have any 
advice for me?

Doug

Hi Doug 

Did you see this message. 

http://boudicca.tux.org/hypermail/jackit-devel/this-month/0063.html

It seems to indicate a working setup (albeit a different card).  I guess it 
might be worth giving it a try.

Dave

    First do what's necessary, then what's possible, finally the impossible.
