[FFADO-devel] Fwd: M-Audio FireWire Solo - Mixer implementation

[Darren A. <dar...@gm...>]

Hey Tomasz,

Pretty interesting problem. I would imagine that the windows driver is
sending some sort of command to unmute the device before streaming audio.

If you could download http://perisoft.net/bushound/ (the free version) and
use it to log the firewire packets through a power cycle of the interface,
then post it here, it may be of some help.

Regards,
Darren
