Re: No sound from usb on Motorola C350 cellphone

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



With an old copy of motorola driver, the usb sound device was
recognized by windows XP, with mixer elements only for the playback. I
was  not able to record from it, playing give no errors, but no sound
either

With the last copy of driver from motorola developer devsite, on XP a
whole new "Motorola Device" is created, with the audio interface
listed on it in the usb control panel, but no audio device is
available for normal usage.

Needs more info, tests?
