ok, I figured out when use conference record, handle->channels = 1, but in uuid_record, handle->channels = 2, so the following code did the trick in fsv_file_write, but I'm not sure if it's the write approach. Why the *len is always 160 in both cases? where the other half channel data goes to? I use play_fsv so the playback should be right. Only tested on 8000HZ right now. If the following code is confusing I can submit a full patch. Thanks.
