- Try changing the sample rate
Like this it works:
$ jackd -R -dalsa -dhw:1,0 -r96000 -p1024 -n8
According to AlsaOpensrcOrg this card has a fixed buffersize of
64KBytes so for the analog I/O you're forced to choose between:
(16 bit wordsize)
--2048 frames and 8 periods
--512 frames and 32 periods
(32 bit wordsize)
--1024 frames and 8 periods
--256 frames and 32 periods
I've set to 96KHz 32 bit 1024 frames 8 periods and it works more or
less nicely. Unfortunately latency is 85 ms and I counted on this card
to provide me a much lower latency.
According also to AlsaOpensrcOrg, with recent enough versions of ALSA
and jackd I could set the number of periods used to any number below
the number of periods created, resulting in much lower latency. But I
don't know how to do this. Any help welcome!
- Try selecting the analog input (you know rmedigicontrol?) or
I did not know about rmedigicontrol! Now I've set input to analog and
I can launch jackd full duplex without delay warnings.
- Try providing a 44.1kHz clock source on the selected
digital input
channel. I vaguely remeber having such problems with my DIGI96/PRO
when there is no digital input (OK, the /PST has analog input in
contrast to the /PRO)
Yep I'm working analog. I purchased this card in order to be able to
output sound via S/PDIF to my minidisc apart from having top class
stereo analog I/O converters.
Cordially, Ismael
