Just got the Revo to replace an ailing SB Audigy 1.  The Audigy was connected via the digital output to a set of Cambridge SoundWorks FPS 2000 4.1 speakers.  The Revo is connected to the same speakers via two analog 1/8" wires.   This analog connection sounds far better than the Audigy's digital connection.  The Revo is fantastic.

I've noticed the following issues with MC, however:

• ASIO has skips, clips, and clicks.
  
• the DSP studio doesn't seem to have any effect.
  
• DirectSound sounds BETTER than ASIO.
  
  I am not against using DirectSound with MC but I've always been under the impression that ASIO was better.  I was able to use ASIO with the Audigy which did sound better than the Audigy using DirectSound.
  
  Am I missing something here?
  
  This is a brand new rev3 board using the latest drivers from M-Audio's website.
  
  Thanks!

No takers?

I wasn't able to get ASIO to work at all with my Revo and 9.0.  I'm using driver 5.10.00.0035 since the latest driver broke the "Enable Monitoring" via SPDIF.

No clue which channel SPDIF is and I tried all 0 -14 and restarted MC.

You might want to try and increase the DMA buffer.

Here's the manual link;

I have been using a Revo 7.1 since around March or April and I agree you can't beat the quality of the Audio coming out of the card for the price. I did have a problem with ASIO when I first got the card. I think that was back under Media Jukebox 8. Can't remember if it was MC 9.0 or the strat of the 9.1 betas but I am running ASIO now under the current 9.1 builds w/o an issue. Did have a small problem w/some of the 9.1 betas that would play slow on the first track after booting the PC but a stop and start of playback would cure it, anyways that issue has been gone in the last several builds.

Not sure why your having ASIO issues, which ver of MC are you running? Might also be a horsepower issue. I am fortunate enough to be running a P4 3.2 with Hyperthreading and when I am running a lot of background tasks that are pushing CPU usage to 100% I sometimes get a pop or 2. THe Revo does rely more on the CPU for proccesing than the Audigy cards do.

I read in AVSForum that ASIO doesn't work via SP/DIF - not sure if this is fact though.

Can't comment on spdif as I have no way to test it. If I have anything bad to say about the card it would be the limited in/out options but again for the money the sound is awsome even w/analog outs.

I'm running an Athlon XP 2100+ with a gig of DDR RAM.  It's a pretty nice set-up.  I plan to upgrade to a Barton 3000 in a month or so so I can play Half-Life 2 and Doom 3.  But I'm being tangental here.

I'm not using SPDIF because my speakers' connection doesn't support it.  It uses a 9-pin DIN connect which came with a convert to 1/8" inch rather than RCA for use with the SBLive/Audigy series of cards.  As you wrote, the Revo sounds better via analog than the Audigy did via SPDIF.  Instead of hunting around for a way to interface the Revo with the SPDIF on these speakers, I'm probably just going to replace the speakers.

I'm perfectly happy with DirectSound output.  I'll mess around with the ASIO settings although, like I wrote, I noticed that MC's DSP studio has no effect on Revo's ASIO output which makes me less inclined to use it.

I'm always running the latest beta of MC, btw.

Yeah I had (actually still have sitting in the box) a pair of those FPS2000 speakers. That digital connnection is typical Creative not standards compliant w/anything but thier cards. It acually isn't technicaly a spidf connection but individual front and rear signals sent in a digital format. That's why they need so many pins. I dropped the FPS2000 for a set of Logitech Z560's that don't have any digital interface.

On the ASIO I did have to set the ASIO buffer to 2048 in the Revo driver. I am using DSP w/ASIO ok also.; In the output format I have it set to 24bit, source number of channels and 48000 Hz sample.

I also have the SRS circle surround on in the Revo driver.

Thanks, I'm currently giving those settings a shot and so far it seems to be working a lot better.  I think it was the ASIO buffer adjustment in the Revo drivers that did the trick.  I'm going to experiment with the DSP studio a bit later as what I'm listening to right now is practically a mono recording (some unreleased Iron & Wine songs).
