ok I just built a new kernel.

I started with 3.4 then applied the rt7 patches then merged the topic/misc
tree from sound (to get the ftu fixes from felix and daniel

so I have 3.4-rt7+sound/topic/misc

checkout v3.4 tag then apply the -rt patches using quiltapply then merge
sound/topic/misc

This all seems to be working ok. if I start jack with anything less that
128 samples It starts but I get no audio and lots of xruns (this is the
same as on previous kernel 3.4-rc4-rt5)

i've run jack_iodelay through a loopback (TRS from output 3 to input 3 on
the back of the FTU) for several hours without any problems

Felix,

the effects controls are not obvious to me I thought there were independent
fx sends for each output so expected 16x4 new controls plus the returns but
maybe that's not howitis.

also has anyone looked at how metering is reported on the wire?

Grant.
