Hi. I have an early Raspberry Pi Model B that along with a Displayotron 3000 has been my Internet Radio for a long time. It ran Raspbian and the other day I did a “sudo apt-get update”. I do this quite regularly but this time I got the following bunch of error messages
amixer: Unable to find simple control ‘PCM’,0
amixer: Cannot find the given element from control default
Traceback (most recent call last):
File “./radio.py”, line 55, in
10 # Idle after 10 seconds
File “/usr/local/lib/python2.7/dist-packages/dot3k/menu.py”, line 114, in init
File “/usr/local/lib/python2.7/dist-packages/dot3k/menu.py”, line 166, in _setup_menu

mode = subprocess.check_output(“amixer cget numid=3 | grep ‘: values=’”, shell=True)
File “/usr/lib/python2.7/subprocess.py”, line 223, in check_output
raise CalledProcessError(retcode, cmd, output=output)
And now my Internet Radio doesn’t work. I am not a Python Guru, in fact I am not a guru of any sort. Can anyone give me any pointers where the trouble might be? I rebuilt the whole caboodle with the latest Raspbian but got exactly the same messages.
I have now created a really simple Radio but I cant let the Displayotron go to waste.
