I've been having a problem recently with my volume on my laptop, a HP M6-1125dx. I have noticed that slowly over the course of a few days I have to keep turning the volume up higher and higher to have the same volume come out of the speakers. I used to consistantly be able to keep my volume around 15, but now I''m having to turn it up to 40 or 50 after a few days. It goes back to normal after a restart though (even a 'soft' restart) and then blows out my ears because either I've forgotten to turn it down before restarting or windows did it to me automatically.
Does anyone have any ideas what could be causing this? I have no idea where I should start since I couldn't find info of anyone having a similar problem.
