Sound driver gone

[blarmy]

I own a Mitac Mio P550 with Windows Mobile 5.1.195 build 14929221
and i uninstalled what i thought was a MP3 player, as it turned out
it was a bluetooth application and for some reason there is no sound
anymore at all.

When i redirect the sound using a program called audioroute, i get the
following message - Fatal error - DynRilDll.dll or Ril missing.

As Activesync stopped working years ago and there was no recovery cd
or OS with the device , i cannot restore the system, as i was told by Mio
support.

I understand it is possible to do a hard reset, but i would lose everything else on the device. So i hope there is a workaround!

Well you can backup everything you need and then do hard reset

No, some devices hang and wont boot anymore after a hard reset
