Nearly finished getting my e6320 working nicely on mavericks. Only issue, and its a bit weird is that the volume setting can be changed by volume controls next to keyboard and on drop down, but volume output remains unchanged through out the range. i.e. can change the control but the actual loudness is on full all the time. Any ideas anyone? Finally got sleep to work.which is nice, but need to find solution to this. Any one else had this on this model or similar.
