fireberd The mulitmedia audio controller is part of your sound "card". If you have the standard audio (on the motherboard and the Speaker connection is on the motherboard I/O panel) you have the Analog Devices audio. If you have an optional sound card - the speaker jack will be on a card in the I/O expansion area of the PC, if you moved the PC that sound card may need reseating. Just moving the PC would not affect the standard Integrated (on the motherboard) audio. However, if there was rough handling of the tower PCI sound cards could have been loosened.
