### Brief description of your issue

Package:
CreativeTechnology.OpenAL

Issue:
The installed version of OpenAL cannot be detected by winget.

Steps to reproduce:

1. Install OpenAL:
winget install CreativeTechnology.OpenAL

2. Run:
winget list OpenAL

Result:
Name Id Version
OpenAL CreativeTechnology.OpenAL Unknown

Expected:
Version should be detected as 1.1.

Additional information:
The uninstall registry entry exists:

HKLM\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\OpenAL

It contains:
DisplayName = OpenAL
UninstallString = "C:\Program Files (x86)\OpenAL\oalinst.exe" /U

However, DisplayVersion is missing.

Adding:
DisplayVersion = 1.1

to the registry fixes the detection problem.

Suggestion:
The package manifest or installer metadata should be updated so that winget can detect the installed version correctly.

### Steps to reproduce

DOS command when the OpenAl app is installed:

Winget upgrade --all --include-unknown

### Actual behavior

OpenAl is installed every time I update apps using the dos command above

### Expected behavior

No updating for an app that is already up-to-date. Thank you!!

### Screenshots and Logs

_No response_

Inspect the CreativeTechnology.OpenAL package manifest and its installer metadata, then compare them with the reported OpenAL uninstall registry entry. Verify that the installed version is detected as 1.1 and that winget upgrade --all --include-unknown no longer repeatedly reinstalls the package.
