main/alsa-utils: further improves to card number extraction regex

Browse Source 
On systems where the soundcard longname also contains digits, the
regex added in !87552 could also match that longname.

All of these issues starting surfacing now because with release
1.2.14, alsactl has gotten more strict about situations where
passed sound devices are not available in kernel.

For an exact description of the file format refer to:
