I have a fa-101. To change the samplerate you have to turn the knob choosing
samplerate, then turn off the card on the back side wait a little while and
turn it on again. Then change the samplerate in settings in jack and then
start jack.
Hope it helps..
I record in 88.2Khz on Ubuntu 10.04 via Jack, works very well
Kind Regards

Hi try:
- stopping jack
- unplug the card
- change the sample rate knob
- replug the card
- change the sample rate in jack settings (or in jackd command line)
- start jack
Does it work?

hallo list,
i borrowed yesterday an edirol fa-101 in order to try if it will work on
my sidux/aptosid mix.
after some tweaking around and reading errors in qjack's messages window i
get it to work really nicely in 48kHz mode. with all other sample rates
which the card seems to be providing ( and is providing on my friends
mac...) i could not get it to run.
on a ffado page the card is listed as 'full supported', so i understood
that also different SR should work. i also realized that turning the SR knob
on the card does not changes nothing and that the SR is given in jackd's
command line.
could someone who is using this card please make some comments on this?
cheers,

Hi Thomas, why do you use 88.2k as your samplerate? Just curious; I use
44.1 if I'm going to CD, 48 if I'm doing pro video, and 96 or 192 if I want
really high fidelity- but I've never used 88.2.

its 2x 44.1 so that resampling to CD format is very artifact free, but
you get the benefits of a higher SR.

I have never noticed any artifacts with downconverting of samplerate, except
on lower-quality Windows conversion software and early versions of Steinberg
Wavelab (no relation!). Upconversion is another story....is there a quick
and easy way to measure if conversion artifacts are present in an audio
file?

"quick and easy" - I don't think so.
http://src.infinitewave.ca/ provides a nice analysis of SRC code.
Note that 'libsamplerate' is filed under 'secret rabbit code' there.

The only quick and easy way I know of is with tools that are part
of sndfile-tools:
http://www.mega-nerd.com/libsndfile/tools/
Two programs in this tools package (sndfile-generate-chirp and
sndfile-spectrogram) were written to create spectrograms similar
to the ones here:

Fons and I have both written high quality resamplers and we both
agree on this issue :-).

I use 88.2k because its far better than 44.1k and the files not get as big
as 96k.
Im not very into this stuff, but you can certainly hear the difference. If
you eq in 44.1k you get that early nineties techno high end. Nice for some
things but very bad for accoustic instruments.
A guy tried to explain me once that when you eq digitally it distorts well
under half the samplerate and under 22k is audible. Dont know if its true
but never the less you can hear a big difference...
Off course I end up in 44.1k 16 bit for CD, but that doesnt mean I have to
edit in 44.1
