I'm running Linphone on an Android device which will only record sound
in 8000Hz. To make the microphone work, I added the following line to
mediastreamer2/src/audiofilters/devices.c:
{ "2N", "IndoorTouch", "omap3", 0, 0, 8000 },
This made the microphone work, but it has the side effect of increasing
audio playback delay from an almost-acceptable 0.8 seconds to almost 2
seconds (tested using mobile phone -> sip). This is very annoying during
video calls, as the video has no noticeable delay. Am I using the right
approach, or is there a better way to override audio recording settings
without affecting playback?
