On my system, analog output works, but the volume of the headphone output is very low. Internal speakers work well, and the volume level is reasonable. However, even at 150%, the volume of headphone output is barely audible (alsamixer
command line utility also at full volume).
Is there a way to set a constant boost or pedestal to the headphone output? What I mean is, applying a strengthening effect to the baseline to which the sound levels in the volume mixer are compared.
There seem to be some reports relating to this on Launchpad - does anyone know of a workaround or solution?
Edit: I forgot to mention that sometimes, when the speakers are enabled (the output is set to "Analog Output"), there is also sound from the headphone output - in these cases, the volume level is a-ok in the headphones as well. However, having the speakers on all the time can be a nuisance.
