no sound Sound problems in Offline Mode

[Nickname]

Whenever I run a modpack (any modpack) while Online all the sounds are okay, but when I play in Offline mode there are no sounds at all, not even in the main menu or ambient sounds, complete silence.

I have little time with internet connection so I commonly play in offline mode, and as you can see, without the sound.

I would lke to know what could be causing this and how could I fix this, I've already tried re-installing modpacks and changing their versions but happens with all the modpacks I have installed (all of them are "official" modpacks that come with the platfom {Tekkit, Tekkit classic, Jogbox, etc...}) so I think it could be a problem with the platform itself.
I'm using the maximum (1gb) storage option, just saying.

I have quite the beefy computer, HP Envy 15, AMD version. (Not Nvidia+intel) With 16GBRAM.

I've seen people are having similar problems with their audios but have found no solution.
Would love if someone could take a look inside the platform, there might be something out of place [more likely with the offline mode]

I'm really starting to miss the sound of blocks being mined.
