I am not claiming the "wrong" settings would not help. The main thing is that it should be possible to achieve the same situation with other settings, while keeping the audio path more sane. If it works for you, fine, but it's not exactly how the audio path should be configured in general. I did use "wrong" settings myself to a satisfaction for a long time, but they shouldn't be used in general. If you see http://www.mail-archive.com/community@lists.openmoko.org/msg58185.html - for example the same effect as raising control.12 from 5 to 7 like some people do when they feel they have too little microphone volume can be had by increasing control.5 by 6 values, but without having additional stage of amplifying (keeping control.12 at 5 means 0dB). The exact effect of setting Mic Sidetone Mux (control.63) to "Right PGA" instead of "Mic 2" is not known, but it uses a wrong audio path and a similar way of lessening noise and mic volume should be done by using control.5 (mono playback) instead. I have also experimented with these on my A5 + buzz fix, and have not found there is any way to "cheat" the system so that using wrong audio paths would magically generate better audio quality compared to using correct audio paths (control.48 '3', control.12 '5', control.63 'Mic 2') and compensating with control.5 to the level wanted. And even if there was, my point is that the default configuration should be for A7, if there is only one configuration by default. Sorry for stating the information "misinformation" so strongly - I don't claim the information couldn't help some people finding values that happen to work for them, it's just not the optimal way to do that. -Timo _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
