That is the Video Player's issue, (which has no ASIO support)
anyway I don't use VAC.
Some Video player should have ASIO support.

Multiple clock crystals, clock logic, PCI logic, drivers for all major OSes, datasheet, all is there ready to use and the price on ebay is negligible.
That's what I am doing at the moment.
Envy24HT I2S from the resistors next to the chip to AK4396 Dac board.
My other boards will arrive next week I hope. Then I will evaluate
the sound to my QA550 SD player. If this solution holds up, then three AK4396 boards will be connected.
I also got LVDS chips from TI to evaluate differecial I2S over a longer distance.
I will report back when I am done.

Hi Jim
Now I'm converting my own SACD to ISO format.
By foo_input_sacd, I can play it with 88.2 on sub small speaker.
So I need sample rate changes to be implemented. Now I'm testing.
Also I added one more parameter bar, to change TAPS 1024/2048/4096/8192.
After some test I will post new version.
maybe I can not use 8192TAPS/192/4Way until 2015.

HI Koon
If you are planned to compile a new version of VST_SSEFIR , could you change the accuracy of the frequency parameter bar ?
Around 200 Hz , the other frequency available is only 160 or 240 Hz.
10 Hz accuracy at 200 hz will be more convenient ...

I modified value-to-Freq routine,
more accurate. Please note that Filter curve = about 20dB/20Hz.

if (ret < 75.0f) return 70;
if (ret < 85.0f) return 80;
if (ret < 95.0f) return 90;
if (ret < 105.0f) return 100;
if (ret < 115.0f) return 110;
if (ret < 125.0f) return 120;
if (ret < 135.0f) return 130;
if (ret < 145.0f) return 140;
if (ret < 155.0f) return 150;
if (ret < 165.0f) return 160;
if (ret < 175.0f) return 170;
if (ret < 185.0f) return 180;
if (ret < 195.0f) return 190;
if (ret < 205.0f) return 200;
if (ret < 215.0f) return 210;
if (ret < 225.0f) return 220;
if (ret < 235.0f) return 230;
if (ret < 250.0f) return 240;
if (ret < 270.0f) return 260;
if (ret < 290.0f) return 280;
if (ret < 310.0f) return 300;
if (ret < 330.0f) return 320;
if (ret < 350.0f) return 340;
if (ret < 370.0f) return 360;
