I have crackilg sound... so I want to figure out what to do... I installed dictator (just not to spend tons of €) and then I play with alsamixer opened. Now the questions:
1) How do I set a numeric value in the gsmhandset? 2) I set New value: 63:'Mic Sidetone Mux':1:3 but it seems it's not persistent, if I open alsamixer i find Mic2 and not Left PGA... wtf? 3) It seems that my audio is everytime over saturated, that much that crackles... any idea? d (it's about an year that i own this fr and i still don't use it as a phone... wtf! :P) r...@1407.org ha scritto: > Experiment: better sound on remote end > http://blog.1407.org/2009/12/02/experiment-better-sound-on-remote-end/ > > One of the problems people complain about my calls from the Freerunner is > *bad*sound*. > Lot's of background noise, static, etc. I'm not talking about the familiar > buzz problem, > as I've had the buzz fix applied to my phone. > > http://picasaweb.google.com/RuiMSeabra/DebConf9OpenMokoBuzzFixParty# > > However what I found to fix this problem on > my phone model (GTA02v5 + buzz fix) goes totally against the official > information. > > http://wiki.openmoko.org/wiki/Neo_Freerunner_audio_subsystem#Alsamixer_channel_controls > > So much so that there's at least one person who, from his very good knowledge > about this > subject (Really!
