rme9652 driver vs kernel

[nick mainsbridge]

hi,

the rme9652 driver has been changed in kernel 2.6.15 to use the mixer
interface for the hardware monitoring switches. the fact that this card
has no mixer is probably not worth mentioning at this stage, but it
means that hardware monitoring in jack will not work with these cards
post 2.6.14.

i can't think of a way around this for jack, but here's the patch to
make it work again for affected users (attached).

So, using the HDSPmixer tool that comes with alsatools won't get around that anyway?  I don't use hardware monitoring with jack, I just monitor via either the spdif out to my mixer or the adat out to each channel.  To be honest I don't actually know what hardware monitoring switch would do for me...it seems I'm monitoring with my hardware fine as it is?

the rme9652 is not the same card as the hdsp9652.
the rme9652 has no mixer, as i said earlier, and there is no tool like
hdspmixer for this card.
the end result for users is that they cannot punch in using ardour and
hear the input signal in certain sensible configurations (like
monitoring through a mixing desk).
