You can't really call the Revo a true ASIO supporting card when it doesn't implement it correctly. I'm truly annoyed that the ASIO implementation hasn't been fixed yet- and I've been complaining since day 1.

That said, I can't get Winamp working w/ASIO because it gets stuck in some sort of loop- it doesn't play anything. Foobar works just fine. There are enough plug-ins for Foobar now so it does a pretty good job, especially when padded to 32bit.

Hi DTSman.

I haven't tried the spdif output. I use analog out at the moment. About the MAD decoder, you can get it from here:
http://www.mars.org/home/rob/proj/mp...%200.14.2b.exe

Make sure you set the MAD to 24bits and priority highest, check auto clipping attenuation, uncheck display average bitrate.

Also i suppose you have the ASIO plauin for winamp?

Cheers.
Kenn.

Thank you k3nnis, I will try it :)

Yes i have ASIO plugin for winamp and Foobar. if I understand MAD is a codec for MP3 only?

You'r right but the revo is 7.1 ready contrary to the Delta 410, isn'it?

ASIO and spdif is the only real bug I know with revo :(
The 410 is 7.1 capable with bass management and individual channel volume controls.

I know it's not as cheap as the Revo, but the M-Audio Delta Dio 24/96 supports ASIO and Kernel Streaming over SPDIF, and also gives you a TOSLINK OPTICAL output.

I like optical so I don't have an copper connection from my PC to my expensive receiver.

The different technologies (toslink, glass, copper) have different bandwidths, and reduced bandwidth (as with toslink) can cause greater interface jitter. Properly implemented SPDIF over coax is widely accepted as a better alternative to toslink. That being said, if you have unresolvable grounding problems that introduce hum or other noise problems with coax, toslink is the lesser evil.

I had no idea, I thought digital numbers were digital numbers.

I could hear no difference on my system between coax and optical connections.

How does this jitter manifest itself?

Here's an interesting source of information on the sound of jitter.

Could someone please explain to me what these bit settings in MAD actually applies to?
I am using kernel in winamp through spdif with revo, and it doesn't work with MAD setting at 24bit but works only with either 16 or 32bit. However, asio works fine with any setting except, obviously, none in spdif.
What difference is there if I use 32 instead of 24 bit?
Yes, I am a newb in need of help.
thanks in advance.

Hi Dtsman.

no problems. Let me know what the sound quality is like compared to kernel straming?:) Probably can't tell the difference. I think MAD is for mp3 only.

chinnei: i am not sure what is the difference in using 32bit instead of 24bit. But since the revo is a 24bit soundcard i use that.

Cheers.
Kenn.

I am sorry, I am late for the test. I will test MAD as soon as possible ... :)

Hi Kenn,

I am trying MAD plugin for winamp. I have setup MAD plugin as it said in readme file : 24bit, highess etc...

MAD is an input plugin. So we must choice a output plugin to work with.

First, I check MAD input and DirecSound ouput plugin. It is working perfectly. Using spdif output of the revo, and compare to Foobar 2000 + Kernel Streaming, it is really difficult to ear the difference.
Then I select stereo analog output in revo setting and retry the both software. I think foobar2k+Kernel Streaming may have better sound.

Then I tried to use Winamp+MAD+ASIO+Stereo analog output but the sound was not very clear, very strange...

Finally I think I will stay with Foobar and KS (24bits padded to 32bits). I am sad KS doesn't work clearly with winamp, because, with winamp I can easily display files informations on my small LCD 2*20 display :)

Do what must be done. Do not hesitate. Show no mercy.

I am running Winamp+MAD+ASIO+Stereo analog output with no problems (no spdif tho) :( ). It sounds better than my standalone cd-player.

I have yet to try Foobar + KS since my wife likes Winamp. :/

Hi,

what is your ASIO and Winamp release?

Hi DTSman.

I am using ASIO+MAD+winamp and i get very good sound, i think as good as my standalone cd player if not better. I have a low-mid end cd player, NAD C521i. I think it comes with 20Bit DACS. Just download the latest ASIO.
The one i have is 040. Winamp 2.91 here.

Do you have icq or msn messenger or AOLIM?:) I could help you there if you have any problems.

Cheers.
Kenn.

Hi Kenn,

I have just send you a MP ;)

If I remember my ASIO plugin release is 033 ... it may explain why my sound was not clear.

Me too I prefere the Revo sound (spdif output enable) to my standalone CD or DVD player (Panasonic).

New Winamp and Foobar ASIO plug-in is out with SSE and SSE2 support.

Winamp 5.0 release is out as well (I finally got it working). Sweet. Video with ASIO audio output.

Does someone try to use M-Audio Revo + Winamp + Kernel Streaming Plugin + spdif output? Does it work?

Kernel should work fine with the spdif as there really wasn't a problem with it, or was there? I thought that asio's the one that didn't work with the spdif.
I am also curious about this, was this bug fixed at all? any updates?

I am using Winamp 5, Kernel Streaming, the M-Audio Revo to my reciever through SPDIF. Plays my DTS CD's from the player or ripped to the hard drive, so I am assuming that this works and has sucessfully bypassed Kmixer. Hope this helps. Sounds awesome, and was easy to do.

winamp5 + kernel streamin plugin + SPDIF does not work for me. I am stuck at winamp 2.91.

Are you doing anything special to get it to work under winamp5?

dm,

nope, nothing special that I can tell. I just downloaded the latest version of wianmp (downloaded it yesterday) and the KS plugin. I did have to download the cd reader for it to work from the cd...thought that this was built into the latest verisons of winamp these days?

hi

My findings so far:

Winamp 2.8x + out_ks.dll crashed my machine numerous times with BSOD's
could not even play mp3's.

Winamp 2.9x + out_ks.dll crashed my machine numerous times with BSOD's could not even play mp3's.

Winamp 5.x same as the above.

J.P media player 10.xx beta + asio2KS, same config as the first post crashed my machine with a BSOD.

J.P media player 10.xx beta + Asio4a crashed my machine with a BSOD.

J.P media player 10.xx beta + wünchen Asio crashed my machine with a BSOD.

Foobar 2000 + foo_ks_out.dll could play mp3's and could play the ripped file from HD but there was no sound, the downloaded snippets of sound from the first post, played flawlessly.

Unless mentioned mp3's refused to play, same as the ripped DTS discs from HD and directly from the player. Im lost for words I simply can not get these DTS discs to play. So an comments and suggestions would be much obliged.

TIA

When you have numerous things (which work fine for others) that are causing crashes and BSOD, it's time to reformat & start again.

If you are otherwise happy with your configuration, consider Ghosting it for subsequent restoration, but I highly suggest formatting the C: drive, reinstalling the OS (and critical updates and drivers) and THEN try the same configurations (as documented above) and see if your machine still crashes. If so, it may well be a (soundcard) driver issue.

Here's another thing that may cause a crash with the Winamp KS plugin--two sound cards. I have a P4PE motherboard and when I tried the KS plugin with the onboard Soundmax and Revo active, it would always crash. When I disabled the onboard solution (in control panel and Bios) it worked fine.

Hope this helps.

This thread is important for those still trying to figure out bit-perfect audio. The recent discussions on the Envy chipset based soundcards could use this information.
