Hi.
I have descovered that the alsa hw device specifikation is wrong in the
man page.
> -ao <driver1[:suboption1[=value]:...],driver2,...[,]>

this should be -ao alsa:mmap:noblock:device=hw=0.3
> Sets noblock-mode, mmap-mode and the device-name as first card, fourth device.

This should be Sets the device name. Replace any ',' with '.' and any

The following don't give any sound
