Custom sounds in maps problem

heyo, i have a problem with an error ive found some weeks ago, i already searched for the error on google but nothing useful appeared

The problem:

If i use a custom sound in a soundscape script or on a “ambient_generic” (sound entity) everything is fine so far also ingame, but if i get the custom sound into the .bsp file (map file) i always get this error ingame if the sound was triggered

“Error reading PAK file header! CUSTOM_SOUNDPATH ( 4 Signature: 10, ID: 1326, Method: 0, Compressed: 43388, Uncompressed: 36 )
Header Updated: Our offset: 4, Dest Bytes: 4, Bytes: 4, PAK Offset: 95329047
NEW HEADER! CUSTOM_SOUNDPATH ( Signature: 67324752, ID: 1326, Method: 0, Compressed: 43388, Uncompressed: 43388 )”

any ideas?

It’s nothing, you can ignore it as long as the sound works.

Alright thanks
