Attached to the monitor, there is my speakers that I can use to listen to music that is transmitted via DisplayPort (or HDMI). Starting with Ubuntu 12.04, Ubuntu can transmit audio via DP. However, when going into standby - either via inactivity timeout or via closing the lid - I hear horrible sound garbage. This is quite loud and can possibly damage speakers and/or ears, depending on the sound level of whatever I heard before.
