One additional wish for the channel map API: functions for converting
between snd_pcm_chmaps and (machine-readable) strings. If channel map
information is added to UCM, the UCM code will have to parse the channel
map specifications, or if they are exposed as unfiltered strings to
applications, then applications will have to do the parsing. In either
case, having readily available functions to do the parsing would be
useful. Applications may also want to convert the chmap into a string
for logging purposes, for example.
