submission:raw_devices_dmi_json: Add the boot mode info to the BIOS dict
This new property comes from inxi which can take the following values:
- BIOS
- UEFI
- UEFI [Legacy]
The last one is legacy BIOS boot mode in a system using UEFI but booted as BIOS/Legacy.
It is added to the existing json directly into the BIOS dict.
bin/audio_test.py: Fix the "Unable to control recording volume..." bug
Fix:
1. Remove the method parameter from PAVolumeController.__init__():
Assum PAVolumeController class only be used in this audio_test.py.
2. Don't check the return value of self.method(command):
In PAVolumeController._pactl_output(), when failed to execute the pactl command the exception will be thrown.
3. When pactl command fail (after retry 3 times), let audio_test stop.
Original issue:
In PAVolumeController class:
In set_volume() and mute(), the self.method(command) returns a zero-length string.
So, the set_volume() and mute() always return False. Then, in get_volume(), the self._volume always won't be set.
This is the root cause of the "Unable to control recording volume..."
issue.
More detail:
1. There is no ouptu from the `pactl set-souerce-volume ...` command.
2. The PAVolumeController._pactl_output fucntion will return
subprocess.check_output(). The subprocess.check_output function return the output of "command".
