[Bug 1946268] [NEW] autojack fails with "local variable 'drates' referenced before assignment"

 

Public bug reported:

Following upgrade to 2.2.5, opening studio-controls shows status is
undetermined. Jack cannot be started, stop has no effect. Investigation
of "systemctl --user status studio" shows autojack has failed.

Attempting to launch autojack shows the following, which looks identical
to the output from systemctl:

$ autojack
starting up
install path: /usr
sending quit to any old autojack
old lock file found, killing old pid

Lock file created
logging started
Traceback (most recent call last):
  File "/usr/bin/autojack", line 1713, in <module>
    main()
  File "/usr/bin/autojack", line 1662, in main
    phones_check()
  File "/usr/bin/autojack", line 1498, in phones_check
    import_config("phones_check")
  File "/usr/bin/autojack", line 399, in import_config
    import_device_array()
  File "/usr/bin/autojack", line 240, in import_device_array
    get_dev_info(x)
  File "/usr/bin/autojack", line 138, in get_dev_info
    if len(drates):
UnboundLocalError: local variable 'drates' referenced before assignment


Setting importance to "Critical" since this involves a core component of Ubuntu Studio's audio subsystem just prior to final freeze.
