Can you ... var_dump(exec($mixer . ' ' . $command)); I wonder if the output includes a new line which you are not accounting for in the regex.

Haven't tried yet, but isn't that what $ is for? End of line?

$ matches end of line, but since your last match expression is to match explicitly the character '.' before end of line, and there's a newline, it won't match. Again, use trim() to get rid of the newline character at the end of the string returned by exec(). Looking at the output or

And exec only gives one line- the last line of the output of the command. You have to provide a reference to an array for the entire output. var_dump gives: string(41) "Mixer vol is currently set to 75:75"

It also looks like \d{1,3}\. won't match anything in the output string given by the command.
