problem with python3 and scarlett 18i20

[batteur-geek]

Helo I am using python3, and a scarlet 18i20. I got an error in extract_controls().
I have add to print to check the problem
def _extract_controls():
dump = subprocess.check_output(
["amixer", "-cUSB", "controls"])
#print(dump)
for line in dump.splitlines():
print("line : ",line)
num_id, _, name = line.split(b",")
_, num_id = num_id.split(b"=")
num_id = int(num_id.decode('ascii'))
_, name = name.split(b"=")
name = name.decode('ascii').strip("'")
print("name = ",name,"num_id =", num_id)
yield name, num_id

it ends with :
line : b"numid=9,iface=MIXER,name='Master Playback Volume'"
name = Master Playback Volume num_id = 9
line : b"numid=1,iface=MIXER,name='Extension Unit Switch'"
name = Extension Unit Switch num_id = 1
line : b"numid=6,iface=MIXER,name='Extension Unit Switch',index=1"

Hello, I dont know how to propose a pull request. I have modified the script to read the missing parameters. I have not modified the yaml file and the load function.
The modified script is here
