SYMPTOMS

You install a High Definition (HD) Audio function driver on a Windows Vista-based or Windows Server 2008-based computer. The driver can expose multiple non-Pulse Code Modulation (PCM) audio formats and some PCM or non-PCM audio formats that are encrypted.

However, you may notice that the audio application cannot play the following formats:
  • The latest non-PCM formats, such as Dolby True HD
  • Both PCM and non-PCM audio formats that are encrypted

CAUSE

The audio formats that are mentioned in the "Symptoms" section are expressed in a KSDATARANGE_AUDIO structure with a unique SubFormat GUID. The GUID comes from the WAVEFORMATEXTENSIBLE structure.

When the audio application selects a specific audio format to transfer stream data, the audio miniport driver should see the corresponding KSDATAFORMAT structure that contains the specific GUID and other parameters in the miniport’s handlers. For example, the audio miniport driver should see the NewStream() parameter. When the audio driver encounters these parameters, the driver takes some action, based on the specific GUID.

However, in Windows Vista-based or Windows Server 2008-based computers, the system audio stack (Portcls.sys) may pass a KSDATAFORMAT instance with a different GUID to the WaveRT miniport’s NewStream() parameter.

For example, there can be two data ranges that have the same sample rates, but the data ranges have a different number of channels. In this case, the system may detect one data range that is the first data range that matches the sample rate and the sample bit in the array. However, the channel number is incorrect.

Therefore, the audio driver does not obtain the correct data format. Because the driver does not obtain the correct data format, the audio driver cannot function correctly with regard to the audio format that was selected in the application, and the function fails.

    VersionProductMilestoneService branch
    6.0.600 0 . 20 xxx Windows RTM LDR
    6.0.600 1 . 22 xxx Windows Vista SP1 and Windows Server 2008 SP1 SP1 LDR
  • Service Pack 1 is integrated into Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • The MANIFEST files (.manifest) and MUM files (.mum) installed for each environment are listed separately. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files (attributes not listed) are signed with a Microsoft digital signature.
