Current the capture size is 0x6000000, plus playback size (0x6000000) the total size is exceed the maximum buffer size for the sound card. There are several buffer size setup modes for different rpmsg soundcards. For rpmsg-micfil soundcard, the capture buffer size is 0x100000. For rpmsg-audio soundcard, the normal playback buffer size as well as capture is 0x10000. In the case that lpa is enabled in rpmsg-audio soundcard, the playback buffer size is set to 0x6000000 and the capture buffer size is 0x100000.
