I've still not got this working *at all*. I have switched in a new RME 9632
card to compare, and upgraded the drivers on my 2.6.1mm2 kernel to the
latest tarball 1.0rc2 versions.
Still the same issue. Every app just sits there hanging or making no sound
when you ask it to play to the jackplug pcm device. Most recently I
installed alsaplayer and the same happens here - it's own native jack output
layer works a treat, but the alsa output to the jack output just plays
silence (although it doesn't seem to hang the app now...)
I did spot one problem in that I hadn't created a ctl device for my pcm
originally, but my new asoundrc is below and this doesn't play anything...
Does someone have this working *at all* on their system? Could you please
demonstrate your asoundrc and list your soundcard make/model and versions of
drivers.
Thanks
