I think so. The msp3400 is loaded and I tried toggling the mute  
control in sysfs and played with the volume and the various other  
audio settings, but nothing changed.

Unfortunately, I could not get the driver working in Windows (just  
Win98 here). The device works somewhat on the Mac. At least I get  
some audio out of it (so I don't think the box itself is broken), but  
sound and picture are distorted. I believe the Mac driver was written  
with only NTSC in mind and does not handle PAL properly.

If it might help I could try getting my hands on an XP to sniff the  
USB transfers on Windows, but I don't have any experience in that.

Btw, does the device normally disable sound by itself unless the  
channel is tuned in properly (so you don't hear the static)?
