bare in mind I don't know anything about GSM and audio. But in http://wiki.openmoko.org/wiki/Neo_1973_and_Neo_FreeRunner_gsm_modem#AT.40AUL there is an entry for "AGC parameters" that makes me think the chip actually supports some form of ACG, but maybe is not on by default or has the wrong defaults ? Maybe some other hidden AT command... Got now idea how to actually find out about these defaults... thanks for the explanation anyway. Another theory maybe be that the gsm audio setting that we used in the past where mostly in that way to try to alleviate the buzz problem. Now that the majority of users applied the hw buzz-fix, maybe the new audio settings introduced a more noticeble distortion the before ... just a theory. cheers, p -- ---- http://en.wikipedia.org/wiki/Posting_style _______________________________________________ Shr-User mailing list [email protected] http://lists.shr-project.org/mailman/listinfo/shr-user
