ASIO4ALL works perfectly on my machine (Celeron 1800. asus P4SEU2 and TheaterExcel C-media based sound card), but only with old drivers: 6.32. With newer drivers I get bad sound quality, bigger lattency and eved my subwoofer doesn't work(I play electric guitar). Same thing happens with CMI8768 driver which has pretty nice interface and more compatibility with games(EAX and stuff...). I don't know what's causing this and I wonder if that can be fixed in next version of ASIO4ALL.
Thanks.
BTW I must say that ASIO4ALL is a great program. It's hard to find such speed in today's overbloated programs.

First, you will get back your bass/center if you disable the inputs - the jack sharing issue.
The EAX (etc) compatibilty you mention comes at a price: This is all emulated in software, and, as such, makes the WDM driver slower.

I don't think that jack sharing has anything to do with this. I have PCI card with 3 jacks for output and two jacks for input (mic-in and line-in). This card even comes with optical output on a separate daughter-card. And, yes, I know that EAX takes some processor time but that only happens in games. Correct me if I am wrong but I don't need EAX for ASIO4ALL. My problem is that I have bigger latency and not-working subwoofer ONLY with newer drivers for CMI8738 (6.38, 6.39,6.4x), and everything works fine with old 6.32 driver (even the subwoofer). Maybe new drivers suck for these purposes, I don't know, but they are definitely better for everything else except using with ASIO4ALL. So I want to make sure that I tried everything before buying new card.
Thanks again and sorry for bad english.

Allthough you do not need EAX for ASIO operation, the mere fact that it is emulated at the kernel level means that the WDM driver uses some more double or triple- buffering, since these effects are not usually calculated in realtime.
This additional processing stage seems also active if there is no processing at all.
I have a system with CMI8738 on board sound and this one would indeed map the input to the bass/center jack, so you cannot have both at the same time. After all, there's just three jacks ;-)
With your card, of course, that should be different, albeit it looks like the WDM driver handles it as if it were the onboard solution. Is there anything you can configure in the driver, regarding channel asignments? Does recording via MME work while 5.1 playback is active at the same time?

I finally managed to make it work with new drivers by using integrated sound chip on my motherboard for input and PCI card for output. BTW on-board chip is also from C-media - 9738. For my PCI 8738-based card I am now using a driver for 8768 chip that can be found on Soltek's site (try this link: 217.160.208.211/soltek/download/download_all.php?isbn_st=SL-B9A-FGR). Sub-woofer works fine now. Only thing that I don't like is that now I have a little bit more hum in the background when I play my guitar, but I belive that's because of poor quality of on-board sound chip and greater interference than on PCI card. I also had to lower that slider for mic-in input because of very strong bass that sounded bad in final sound that my guitar produced and I had to turn on mic boost in windows mixer because it didtn't work with mixer that came with C-media driver. Anyway, if someone have similar configuration and problem he should try these solution. |
