Yeah mine does the same. I don't think it means ASIO isn't doing what it does. I think Foobar2000 allows use of it's volume slider during bit perfect playback.

I may be wrong but it sounds as good as it ever has.....I'm not too familiar with Foobar even though I use it exclusively

Sorry if I've missed the question - it can be hard to keep up in this thread!

~Phewl.
See my latest post for details on this AP

I have a hard time keeping up with this thread too...when the new DIY thread is born...things should be a lot easier...for everyone

Yea it sounds good to me but if for some reason ASIO isn't working properly then that is not good and I need to get that fixed. Also people are saying that their Windows Volume is not working when using ASIO4All so that is why I asked. By the way I have the ac-1 sound card.

Thanks.
I asked Kingwa for this...all he sent was the useless schematic on the web page. I have a feeling the pin out is exactly the same as the one on Burson Audios site on the cap tweak page. V- and V+ are unchanged and I can't see why any of the other pin assignments might be different.

Wait I'll get a link for you....

There you go Alex

Hmmmm.......you know I think my windows mixer vol also works...maybe I need to look at my own setup to see what gives. I do however have excellent SQ when using Foobar and the Auzen ASIO driver...maybe the latest ASIO drivers allow this function ?

If the AC-1 card has it's own ASIO driver, use it instead of ASIO4ALL.

Can anyone add to this particular discussion WRT questions at hand please ?

Don't let the looks fool you. Once in place and doing it's thing, you'll like it.
Excellent, thanks, Pench. Will get onto it this morning. At least with the open construction it will be easy to clean the tracks with contact cleaner if need be.

How would i find out if my ac-1 sound card has its owns ASIO driver? Yea maybe the new version does allow volume changes through windows but isn't the point of ASIO is to bypass everything in windows including the volume changer?

You would think...it depends on how the driver is written...er coded ? I have no details on the Auzen ASIO driver, just that it supposedly works and is working ?

As you can see I'm also in need of answers....

Need more input from others on this...I'm at the limits of my SC knowledge.

The Alps pot is indeed a SQ upgrade and the price is right

Peete.
Haha, thanks PP. The S-man has a new set of Senn 650s in the air today, winging their way to NZ, woohoo! Might as well go all out on the headphones and upgrade the amps 'n' things as time goes by. Saw the pics of Little Dot VI yesterday ............ sweeeeeeeeeeeeet!!!! Wow. What a gorgeous unit. Mustn't ..... lust ...... after ...... it, ....... spent ...... lots ...... of ...... money ..... since ....... joining ..... Head-Fi ....... already ............ ooooooooh but it is sweeeet .......

This thread might explain a bit more about ASIO4All.

Yep I just did this mod the other day S-Man. It a big improvement over the old pot, the SQ increase is noticeable and the channel imbalance is gone. I happen to like stepped volume controls... Now about that shaft length and new knob Sigh, it always something....

It's a five minute job. Clean the side of the pot (with cleaner of choice) for the casing ground wire. Scuff it a bit so the solder will stick...learned this the hard way

Excellent NED !!!! Reading it right now

Peete.
post #6073 of 9354
Yea I just read that and I think my asio4all is working. When I change the volume on "wave" it doesn't affect the volume at all. Guess I am getting Bit-perfect-playback. Thanks peete and nedman and also the creator of that thread.

Beauty, mate, I'm going to get onto that in just a tick or two. On to it with the case ground, almost forgot that. I actually like my old knob .......

Oh, my new shaft is too long! Might have to trim it a bit (ouch?).

Thanks PP. Finally 1 SUN+2 earth now. Did not do any power mod yet. Already love it with D2000. HD650 still works horrible - but I never looking forward to it anyway.

Where is the best ground point? did you guys figure out it yet?
Also how do you layout 3 unit in Zero? I do not feel engouh space.

Also what is surprised me is after switch my vol nob do not needs to change still 10 o'clock position.

Short feeling:
Compare to duet:
Bass is a little better. Sound stage is way better. But mid-high detail ,Worse a lot , maybe need to burn in.
