Jamcast

One thing i could do and haven't done is uninstall and reinstall with the new version. I had been installing over the top.

I don't have any other physical hardware I can test on. This is the only physical machine I have that i can test with. Any other testing i could do would be with a virtual machine, which doesn't really test a real world scenario.

Nice thing about Windows 8 though is that i can put Win7 in a virtual machine and that'll still work, but I'd rather not have to go that route.

Hi Scott,

I have just installed the RTM build of Windows 8 and the problem described in this thread still exists. Has there been any progress in fixing this issue?

Thanks!
Philipp

Hi Scott,

sorry for the delay in replying. Yes, I have tried Jamcast on the RTM version of Windows 8 and have experienced the same issues as described in this post.

Hi Everyone,

I have spent many hours on this with no success yet, unfortunately. This seems to be a universal problem with Windows 8, Microsoft's own sample applications are failing as well under identical circumstances.

I am attempting to correspond with Microsoft's experts in order to figure out what to do next. So far I am being ignored, but with persistence I am confident I will get the answers we need here eventually.

In the meantime, I thank everyone for their patience and assure you that this will remain at the very top of my list until it is resolved.

Thanks!

Thanks Philipp!

I think my previous post came off rather harsh, i can be tough finding the right folks to talk to and then actually make contact. It takes time and patience, I know this. To say I'm being "ignored" was a bit dramatic for now.

I'm trying another contact via email today. I'll keep everyone posted.

Thanks!

Hi Philipp,

Thanks so much, I appreciate that offer of assistance.

Good news, I got the right guy on email and am providing him with detailed diagnostics. I might ask you kind folks to do the same, depending on the outcome of this conversation.

Philipp, are you running Win8 on a physical machine or within a VM?

Thanks!

Hi Philipp,

No problem, thanks! We're still awaiting feedback on the performance trace logs I submitted a week ago. The rep from Microsoft who is helping me was out of the office some last week, so hopefully we hear something back early next week. I'll stay on top of it.

Thanks!

Hi John,

This describes perfectly the behavior we are all experiencing -- low CPU but audio frames are missing from the captured output, leading to sound that appears to fast-forward (but at normal pitch). Your jamcast.log should indicate a very high glitch count after the capture stream is closed, each incident represents an audio frame lost. This is indeed limited to WASAPI loopback capture on Windows 8; the way Jamcast interacts directly with your audio interface via Hardware Capture Mode remains as functional as with previous operating systems.

As you see, we're working with Microsoft now to try and resolve the problem. Hopefully it's an easy one for them to reproduce and provide a solution for, but still waiting on feedback. I will keep this thread up to date with information as it becomes available.

Thanks!

Hey John,

If your audio interface has a "Stereo Mix" or "Wave ___" or "What U Hear" recording input, then yes you can use this as an alternative to WASAPI loopback capture. It would be listed along side Mic, etc. If you don't see it, Google for your audio card make/model plus "Stereo Mix" and see if this input is hidden or perhaps available in a different driver.

Regarding trial extension -- absolutely! Just get in touch with me thru here or otherwise when the time comes and I'll take care of that for you.

Thanks!

You're welcome, and we appreciate your business should you decide to pick up a copy of Jamcast.

Yes that's right, if you have it Stereo Mix (or equivalent) will be shown as a recording device right along with mic, line in, etc.

Thanks!
