(b) There is no information in the article indicating that the software failure incident was related to the operation phase or misuse of the system.
Boundary (Internal/External) within_system (a) within_system: The software failure incident with the Pioneer SP-SB23W sound bar was due to an issue with the audio processing on Bluetooth music streaming within the system. Users reported that only the right channel of audio was being decoded when using Bluetooth, resulting in mono sound instead of stereo sound. Pioneer acknowledged the issue and posted a notice on its website for affected customers to contact customer service for assistance [22450].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case was due to non-human actions. The issue with the audio processing on Bluetooth music streaming with the SP-SB23W Speaker Bar resulted in only the right channel of audio being decoded, leading to mono sound instead of stereo sound. This flaw was confirmed by connecting a MacBook Pro to the speaker bar via Bluetooth and adjusting the balance control, which clearly showed the problem without any human intervention [22450].
Dimension (Hardware/Software) hardware (a) The software failure incident in Article 22450 is related to hardware. The Pioneer SP-SB23W Speaker Bar had an issue with the audio processing on Bluetooth music streaming, where only the right channel of audio was being decoded, resulting in mono sound instead of stereo sound. This issue was confirmed by connecting a MacBook Pro to the speaker bar via Bluetooth and adjusting the balance control, which resulted in silence when the balance was moved all the way to the left. Pioneer acknowledged the issue and posted a notice on its website for affected customers to contact customer service for assistance [22450].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in the article is non-malicious. The issue with the Pioneer SP-SB23W Speaker Bar was related to a flaw in the audio processing on Bluetooth music streaming, causing only the right channel of audio to be decoded, resulting in mono sound instead of stereo sound.
