No sound or poor sound when recording TV (Media Center 2004 Edition)

There is no sound when recording live TV or your TV recordings do not have sound when played back. There are two things that can be done to work around this problem:
First, simply leave the Media Center interface open during the recording. Do not start a recording and then close Media Center.
Second, if leaving the Media Center interface open does not help, change the recording quality setting to a different setting. This is done from the TV Settings, as follows:
  1. Open Media Center.
  2. Click Settings, TV, and then click Recorder.
  3. Click Recorder Storage and change the Recording Quality setting to a different setting (Fair, Better, or Best).
  4. Click Save and try recording again.
For more information refer to Microsoft support article 833941 - Recorded TV may be corrupted or may have no audio when you use the "Good" recording quality option.

Popping noise when computer is turned on

A popping or brief static sound occurs when the computer powers on, powers off, enters standby mode, or leaves standby mode.
The sound occurs when the sound hardware in the computer receives or loses power. Some of this power enters into the speaker channels. The amount of power that gets sent to the speakers depends on the type of motherboard, type of sound hardware, and what power management settings are used.
The popping sound does not harm the speakers or the computer and only occurs when power is supplied or denied to the sound hardware. HP recommends that amplified speakers simply be turned down or turned off when the computer is not in use.
For more information use the HP support document Popping Sound When Computer is Turned On.

Can't hear Secondary Language or Secondary Audio Program (SAP)

A Secondary Audio Program (SAP) is a separate background audio track that can contain commentary or an alternative language. You need to turn on SAP to hear commentary or a second language.
If you are having difficulty setting up or hearing SAP through the Media Center computer, ensure you have feature enabled correctly in the Media Center software.
Additionally, if you use a set-top box, satellite box, or cable box with Media Center, you need to enable SAP in both the Media Center software and in your box.
  • For instructions on setting up SAP on the Media Center, refer to the Microsoft article: Change the TV audio settings
  • For instructions on setting up SAP on your set-top box, satellite box, or cable box, you need to consult the manual or instructions provided with the box.
