Since so many people are complaining about the speakerphone echo problem... Here's a flashable zip. It's been forever since I've used edify, and this gives an "unknown error" but the file copies fine. If anyone wants to fix the updater_script to stop it from complaining, feel free to.The problem is that Google left out 2 important lines in /system/etc/mixer_paths.xml when they released the R13 blobs and associated commits. This just replaces mixer_paths.xml with one that works. They used to do this same thing (well, similar) in the lines that were removed .... They just forgot to include the appropriate lines with the change... Easy mistake.BeansTown and I worked to fix this earlier... There are two sections that needed modification, the bottom two items of each section were forgotten about by Google. *shrug*File:*edit*Before the question posts.Yes, this should work on any rom with the R13 changes, including stock. (january updates, unless the rom decided to roll-back their blobs to the december versions).Yes, you flash in recovery.*edit 2*I tested this zip to ensure that it placed the file, and did my testing by manually placing the file where it needed it be. Somehow, I ended up with incorrect permissions on the file after flashing this...which breaks all audio. If this happens ensure that /system/etc/mixer_paths.xml is set to 0644 (everyone at least needs read access). This should mirror the other files around it.I don't have my computer handy to make the zip set permissions
