Guys I've got an issue which I can't get to the bottom of, I was just wondering if anyone had any ideas as to what it could be? OK let me explain the situation: 1) N900 works fine, volume set to max (or anything other than mute). 2) Reboot, N900 working perfectly as before, however now volume is set to mute. I can manually increase the volume and everything including sound still works. 3) Reboot, again volume on restart is set to 0 (even though I turned it up before powering down). Without touching the volume (leaving it on mute) I again power down. 4) Reboot, this time no sound, volume buttons not working, no system sounds (no calls, sms, or any other sound..) and an error message displays when trying to play an audio file ("Impossibile riprodurre il file multimediali. Formato multimediale non supportato." ... that translated : "Unable to reproduce multimedia file. Unsupported multimedia format"). 5) Via the status menu I increase the volume to max (which has to be via the status menu as volume rocker doesn't work) and power down. 6) This time on re-start the volume is set to 0 but it's working, and I can play audio tracks increasing the volume. Basically, if I leave the volume alone and reboot I lose all sound, however if I alter the state of the volume before a reboot (even though it's still set to mute on re-start) it all works. What's going on? I've tried even these commands under the advice of the big D4rklar ... but no results http://talk.maemo.org/showpost.php?p=250867&postcount=1 My n900 takes the command but still the same error.. Tnx again to D4rklar for all the help
