Hi,
since a couple of month i cant use 88200 and 96000 hz anymore .
I tried older version of my kernel, alsa-lib, alsa-firmwares and jack.
That doesnt change anything.

My sound card is an echo layla3g.

In the message box of qjackctl i can read this:

/usr/bin/jackd -R -P89 -dalsa -r88200 -p512 -n2 -D -Chw:1,0 -Phw:1,0 -i8
-o8 -Xseq
jackd 0.116.2

but qjackctl and
#cat /proc/asound/card1/pcm0p/sub0/hw_params 
shows
rate: 48000 (48000/1)

I dont understand what have changed. Any ideas what's going on here?

Thanks,
Guillaume
