Got report about third case of muted device, this time more popular one:

ID 041e:3040 Creative Technology, Ltd SoundBlaster Live! 24-bit External
SB0490

I don't know if those informations help at all, but this is best I can
do for now, because I have no idea what to look for. I have one of
affected devices and I have no troubles with patching/rebuilding module,
so I'd be happy to offer any help, just tell me what logs, device info
or debug outputs are needed and I will do my best to provide them.
