Allows the application to obtain and manipulate lines and mixers for audio playback (rendering). In some cases use of this permission may affect other applications because the audio from one line may be mixed with other audio being played on the system, or because manipulation of a mixer affects the audio for all lines using that mixer. record Audio recording through the audio device or devices on the system. Allows the application to obtain and manipulate lines and mixers for audio recording (capture). In some cases use of this permission may affect other applications because manipulation of a mixer affects the audio for all lines using that mixer.
