The N900 has a problem when using certain headsets, some wired headsets sound ridiculously low and soft when using it with the n900. The reason for this is simply because Nokia placed some limiters on the types of headsets the N900 should use. The problem that the N900 faced with some headsets were imply that the Alsa Mixer was not set to compensate for them. I fixed this problem by simply enabling alsa mixer to compensate for these headsets. How does the script make the n900 faster? It simply does so by turning on/off certain aspects of the alsa mixer sound system and tweaking the virtual memory. The problem with the headsets is a simple matter of the alsa mixer system. I'm not phasing mono stereo together lol, just messing with the alsa mixer system or you can call it the raw equalizer as it deals with raw audio system. About the "wiring / button behaviour" I can't say. By enabling the N900 to compensate for any headset it should in effect fix the button issue, I for one don't have a problem using headsets with volume control but then again I've been using my own script since forever. I'm not forcing anyone to use the script, if anyone finds it to be rubbish then go ahead and call it rubbish :O. If anyone thinks it's fishy then simply don't use it. I looked into the headsets problem as it annoyed me, tried to fixed it and thought I should upload the script here. I'm just trying to be nice and make a contribution to the community.
