I took it out and did a video only capture and lo and behold not a frame lost in 60000.

| I have a Sound Blaster PCI Vibra 128 and a Crystal 8738 card. They both suck. I am going to buy a new sound card, but I need advice on what to buy. I want to keep it under $100, but any advice - even over that price - would be welcome. thanks for the help! |

| I don't have any suggestions on what "to" buy. But may I suggest you "not to" buy any card with Creative or Soundblaster in the name. People used to swear buy their soundblaster. Now they just swear at it. I hear good things about the Turtle Beach cards. The Santacruz I believe. But if you wanna do capture stay away from Creative like the plague. I have enough CPU, Memory, Memory Bandwidth, Disk space and transfer speed to capture 640x480 29.97 44.1khz video in MJPEG or HuffYUV with zero droped frames. But because of the screwed up way the SB Live and Audigy cards behave you get traffic spikes on your system bus due to buggy bus mastering in SB products. I loose a frame for every 2000~4000 frames captured or so. All because of the sound card. Even if I cap without audio. As long as the card is in there it screws the captures up a bit. I took it out and did a video only capture and lo and behold not a frame lost in 60000. |

| Interesting. I have the same issue with my SB card. The quality of audio is sufficient, but it is generally a POS. Turtle Beach used to be Very Good Quality but also quite expensive. Perhaps I'll look into pricing. Hmm, $80 USD MSRP, not bad. I bet it's gonna be good for me. Thanks for the info! |

Soundcards by TerraTec are good. The only downside compared to their Creative equivalents is that the TerraTec cards need more CPU power. But if you have enough CPU power the cards work very nice. Quality is technically seen better ( even though I doubt anybody will notice  ). |

Hi, guys! Do you think it is possible that I have the same problem - only the increase of frame drop is higher after installing the sound card - because I use Creative 4.1 Digital? I have Intel 850 main board with integrated audio and there was absolutely no problem before. If that is the issue, is it enough to disable the card and enable the on-board one - or may be it is better to remove it? I'll appreciate suggestions. |

It is a possibility. Try and see is all I can say. Every card since the SB live has had major problems in those respects.  |

| OK, I tried and it worked. You were right, Neo Neko, thanks. After creating 2 profiles, one with SB 4.1 for playback and one with old on-board card for capturing I lost 1 frame capturing 45 mins from bad quality VHS tape. So it really looks that Creative's cards are not the best choice for capturing. |

| Hey, thank you for tip. I hope that re-enabling onboard audio will fix the problem (when I set 25 fps in Virtualdub I get number from 23 to 26 - even if the audio capturing is disabled). But who knows, Creative announced their new card - Audigy 2. I don't know if it will use the same chipset as current Audigy, if so, frame rate will still be a problem. We should wait for benchmarks. --------------------- using SB Live 4.1 (or 4.0?) |

| P.S. using kxdrivers (www.kxproject.com) will not solve the problem with blaster. |

The SB Live and SB Audigy have the very same chipsets inside. The EMU10x I believe. And to date not all the features of this chipset have been taken advantage of on even the most costly platinum cards creative has put out. Undoubtedly the Audigy2 will be a revision of the Audigy as the Audigy was a revision on the Live. Same problems, new box. |

| ? ! SBL and Audigy has a single quartz of 24.576 MHz and is best for 48kHz If you want to cap in 44.1k a little fix offset comes to your audio lenght. EVER ! The Audigy is still worse than those SBL. I have 32kHz used in history, it is a even-numbered partial factor for this quartz oscillator. Result is a minimized offset of 0.4 sec per hour. If you want to have zero offset please use this version of : http://www.virtualdub.net with the new audio capture sync. developed by A. Dittrich... JoeR |
