My active speakers cost me $300 almost 10 years ago, and they still amaze me. If you do your research you can come across some awesome bang-for-your-buck active speakers.

I agree. My 15 year old Midiland S2 speakers (two satellites and a subwoofer) sound as good as my main system. I only listen to stereo (don't care for surround), so they do me just fine. Plus, they're built like tanks.

P.S. Midiland changed their name to M-Audio a couple years after I bought my speakers. They certainly know PC audio--I have an M-Audio sound card, too, that records and plays at 24/192, and I bought it over 10 years ago.

Hi guys, I'm having a audio hiccups on windows 8 which is not happening on windows 7 using my HDTV through S/PDIF (HDMI).
I tried to isolate the issue, it turns out when I play video on my HDTV and only using speakers there's no hiccups at all.
So I uninstall my audio driver and use the windows high definition driver but still having the same problem.

So now how can I help to fix this one or how can I provide dump file for this.
Thanks!

I would suggest to check DPC.

I haven't yet found an application that properly measures DPC latency in Windows 8 or Windows 8.1. Something changed from Windows 7 and they all seem to report values that are too high.

In DPC website:

Quote:
Windows 8 Compatibility: The DPC latency utility runs on Windows 8 but does not show correct values. The output suggests that the Windows 8 kernel performs badly and introduces a constant latency of one millisecond, which is not the case in practice. DPCs in the Windows 8 kernel behave identical to Windows 7. The utility produces incorrect results because the implementation of kernel timers has changed in Windows 8, which causes a side effect with the measuring algorithm used by the utility. Thesycon is working on a new version of the DPC latency utility and will make it available on this site as soon as it is finished.
As I said it was fine on Windows 7 not in Windows 8, also the latency issues it based on hardware implementation not software.

ever checked this one http://www.resplendence.com/latencymon ?
It claims to support also w8+

Bad drivers also could cause DPC delays, so - you can make it worse also with software

I've tried LatencyMon and it also shows way too high values for DPC latency on Windows 8/8.1.

If I have bad drivers not only playing movies on mpc+madvr+lavfilters would be affected. It would be all applications that output sounds.
As I said it was fine on windows 7 but not windows 8, it is an isolated issue.

Isolated? So you tried other audio decoders, splitters?

This is not what I'm asking:

There's still no way to decode DTS-HD MA in 64-bit players due to the Arcsoft dll being 32-bit only, right?

Yes, there is no 64-bit decoder available yet. But there is a little hope. Someone on the libav-devel mailinglist might be doing an attempt to implement a decoder for DTS-HD Master Audio. If that is a success, then anything based on Libav/FFmpeg, including LAV Filters, will be able to decode it.

In the former case, you'd generally use 3.5 mm cables, in the latter case you'd use HDMI (or TOSLINK if you were feeling nostalgic).
Well technically, giosa is correct in that if you use an AVR with HDMI, you don't need a sound card in the DAC sense. Calling an HDMI output a "sound card" is kinda weird since it doesn't actually do anything except "repackage" the PCM stream for transport over HDMI.

I strongly disagree with that statement and think it's actually the opposite. One good example is the JBL Professional 3 Series which have an amazing performance/price ratio. Besides, there are very good reasons to prefer active speakers over passive speakers in general.

What about other forms of DTS-HD? I'm just curious, and I'm aware that HDMA is the most common variant.

Just spent 10 minutes writing a reply and the forum lost it because a "token expired". It's off topic anyway so never mind, we can agree to disagree.

DTS-HD HRA is already partially supported today.
That is, the extra bitrate extensions and the extra channel extensions can be decoded. Missing is the X96 extension for higher sample rates.

And of course the XLL extension for Lossless is missing, which makes up DTS-HD MA

I wasn't even aware of that, thanks for the information! This is good news...

@nev

Can you share which is the project you are working right now, regarding LAV filters of course ?

In case you missed it, nev took a job with JRiver. He hasn't told us what he'll be working on for them, so we don't know whether LAV work will be affected.
