Multichannel wav muxed in mkv

Description (last modified by )
How to reproduce:
ffmpeg -i input.mkv -i L_R_C_Cb.wav -codec copy output.mkv
The PCM track is created with CodecID A_PCM/INT/LIT and lost the channel map.
That track is wrong extracted/played like with the default for 4 channels: L R Ls Rs
The track must be muxed with CodecID A_MS/ACM to preserve the channel map in the Codec Private data (a copy of the fmt chunk from WAVE_EXTENSIBLE_FORMAT header)
That method is used OK with wformat (from wav header) not 1,3,0xfffe. I suggest must be used also for 0xfffe (WAVE_EXTENSIBLE_FORMAT header)
