Since i update to 5.30 i get this on 2 jukeboxes i have with totally diferent hardware, i open freebox, use the juke as normal, if i close freebox, and try to open'it later my sound hardware its not detected by wmp, therefore i can not play any music, but the sound in windows keeps working ok, its a weird problem i just discover, but if a reboot the pc all comes back to normal. Im using freebox 5.32 on xp service pack 3. Hope its just a bug it can be fixed. thanks.
What if you try to play an MP3 within WMP - does it work then?
Certainly not an E-Touch problem dude, might be a codec issue with WMP. You could try updating it with the latest K-Lite codec pack.
