[Aspire 5742, Realtek ALC272X, Speaker, Internal] Playback problem... The Left speaker works, but the right speaker does not play sound. This computer also runns on Microsoft Windows 7, and there both speakers work

[Gabe Torson]

The Right speaker also does not work on some devices plugged into this computer through the headphone slot. I believe this is a driver problem, but I am not certian.
