The channel selection currently does not work properly when a channel map control is provided but no manual channel map was explicitly requested with "-m".
For example, the CEA/HDMI 6ch (surround 5.1) map is: FL, FR, LFE, FC, RL, RR.
Tested command: speaker-test -D hdmi -c 6 -t wav
Speaker-test tries to play channels in this following order: 0 - Front Left 3 - Front Center 1 - Front Right 5 - Rear Right 4 - Rear Left 2 - LFE
But wav file played on associated speakers are not aligned. Here are the real files played: 0- /usr/share/sounds/alsa/Front_Left.wav => OK 3- /usr/share/sounds/alsa/Rear_Right.wav => OK 1- /usr/share/sounds/alsa/Front_Right.wav => OK 5- /usr/share/sounds/alsa/Rear_Center.wav => KO 4- found file /usr/share/sounds/alsa/Front_Center.wav => KO 2- /usr/share/sounds/alsa/Rear_Left.wav => KO
Issue is that associated wav files ordering is reworked only if channel_map_set variable is set.
Fix consists in allowing wavs re-ordering if a channel mapping as been get or set, i.e. channel_map is not null.
