[LAU] ALSA and RME Raydat troubleshooting

[Vaclav Mach]

Hi,
thanks for your suggestion with dshare. It solved half of our problems.
I can play different sounds on different channels, but I still need to
capture input sounds simultaneously, which is now not possible (device
is busy).
We use x86_64 systems.
And using other period size value I described in my previous reply.
