MultiMC 5 sound issue (slightly my fault)

[NotCero]

I say it's slightly my fault, because I have no internet, so multimc cannot download sound assets.

It gives me an "Unable to play unknown soundEvent" error for any vanilla sound. I am just using the feature of MMC that allows it to discover and use FTB packs as instances. I have no made a copy of any of the instances, because it throws an error stating "Not enough arguments" when I try to start up a copied FTB instance.

I've tried putting the assets folder wherever I could in order to fix the issue, including both the MMC folder, different Jar files (with backups, in case I screwed something up), and in different locations inside the FTB install directory. If I had internet, Multimc would likely download the assets to the correct loacation, but I can't do that at the moment.

Basically, any idea where the vanilla sound assets for the Infinity pack would be stored while playing FTB through MultiMC?

Going through the logs, I noticed I was missing the assets index file, so I put that in, but still no dice. The error no longer shows up, but still no sounds.

I think I can get sounds back through sounds.json and a resourcepack, but I'll have to write it myself, and that will be a giant pain. Any idea what to do?

Multimc says that it is using the assets folder within the multimc directory. "MultiMC/assets"

So why would there be no sound?

MultiMC has a habit of hashing every file it downloads and storing that value to compare against to make sure a file isn't damage. If it doesn't find a file listed in its metacache file, it probably assumes that it's not there at all. At least that's the behavior I've seen before in regards to libraries and things, when I tried to add one manually.

If you're talking about a 1.7.10 pack, you might try inserting this into the metacache file in your MultiMC folder. Just make sure you pay attention to how the file is formatted and insert this appropriately:

       {
            "base": "asset_indexes",
            "etag": "\"92820e5151b5cecc4c67692d9a52ca39\"",
            "last_changed_timestamp": 1403816146886,
            "md5sum": "92820e5151b5cecc4c67692d9a52ca39",
            "path": "1.7.10.json",
            "remote_changed_timestamp": "Thu, 26 Jun 2014 13:49:23 GMT"
        },

This still might not even work depending on the timestamp on your computer, but I suppose it's worth a try. Just make sure you also have the assets copied out of the vanilla launcher to MultiMC's assets folder.

That didn't work, sadly. I ended up having a friend grab the files I needed, and I downloaded them at the library, which fixed the issue.
