Well, if specs says channels is in AOT specific config for ALS, then we
should be what spec says.
IMHO just add "channels" field to MPEG4AudioConfig and set it for ALS.
I think it could be set for others AOT too, it could avoid accessing
chan_config outside and if chan_config is wrong it would be set to -1.
I'd like to hear comments from others.

Ok for the part I maintain.
