Receiving apparatus and control method

A receiving apparatus, comprising:

• an audio output unit configured to output audio corresponding to an audio signal;
• a volume operating unit configured to output an operating value indicating a volume level of the audio according to a user operation;
• a lock controller configured to switch between a non-locked state in which the volume level of the audio can be varied based on the operating value and a locked state in which the volume level of the audio is fixed by a constant lock value for the operating value;
• and
• a volume controller configured to cause the audio output unit to output the audio having a volume level corresponding to the operating value in the non-locked state and to cause the audio output unit to output the audio having a volume level corresponding to the lock value in the locked state, wherein
• the lock controller is further configured
• to switch, when a predetermined operating part is turned on in the locked state, the locked state to the non-locked state for a period of time that starts when the operating value becomes a value that falls within a predetermined range based on the lock value and ends when the predetermined operating part is turned off, and
• to update the lock value with the operating value and switch the non-locked state to the locked state when the predetermined operating part is turned off after having switched to the non-locked state.
