Preview audio in Sounds does not work

Preview doesn't work in the Sounds folder, but it works in Music folder.

Testing on r157 stable and r163 beta, on Chrome and Firefox.

I double-click the file name in the Sounds directory, than the "Audio preview" window appears, the timeline moves and time flies, but the sound cannot be heard.

If I move a file from the Sounds folder to the Music folder, it doesn't help.

Working with a lot of sounds is a bit of a pain. You need to reach to the list of sounds to read what the sound contains. You can live with it, but preview audio makes work easier :-)

Are you sure the sounds are a supported format? Typically providing an example project is the quickest way to answer questions like this and establish if there's a problem.

Here you go:

drive.google.com/open

All my sound are .webm format.

It is strange that some files work and some do not.

Only these files work in audio preview:

- tutut

- foot1

All the sounds play just fine in Chrome for me.

It looks like my Windows 10 has caught stupidity. I started checking and found out that something with the sound driver has broken. For example, watching a movie I can hear music clearly, but the actors are muted so that they can barely be heard.

Sorry for the hassle. I could check on a second computer before and than post a question. It is for me a lesson for the future. Thanks!
