Realtek HD Audio + Windows 7 + ASIO4ALL = Love

[exyll]

I have *excellent* results with the latest beta. The USB latency is GONE and it is stable too as with 2.9 I built up more latency over time with my USB microphone.

I usually have the latency set to around 128 samples for my heaviest setups during live recording.

I really don't notice any delay during live monitoring my USB microphone and my realtek line-in guitar recordings.


Awesome job!


Hope that my configuration details help people optimize their system to get lower latency.


I have the following hardware setup:
- AMD Phenom II X3 @ 3.25GHz
- 4GB RAM
- Samson CO3U USB microphone

Following software setup
- Windows 7 x64 (system rating of 6.8)
- Realtek HD Audio drivers latest version
- Ableton Live 8.0.8 (other DAW's work fine too)
- ASIO4ALL 2.10 beta 1

Following system configuration
- Disabled screensaver
- Disabled indexing/search services
- Disabled Processor Powermanagement
- Set processor scheduling to: Background services
- Disabled (temporarily) the virus scanner
- Disabled all software that I do not need during my audio sessions (MSN, Skype, email notifiers, twitter clients, etc.)
- Set all audio devices to 48kHz 16 bit exclusive mode on the "advanced" tab of the audio ports in Windows "Playback" and "Recording" devices.

Following DAW configuration:
- Using ASIO and selected ASIO4ALL driver
- Set DAW audio quality to 16bit / 48kHz as that is the usb microphone native sampling frequency

Following ASIO4ALL configuration:
- Selected advanced view
- Enabled only the ports I needed (realtek line-in, samson usb in, realtek audio out)
- Unchecked "Always resample 44.1kHz<->48kHz"
- Checked "Hardware Buffer" for my Samson USB mic
- Checked "Allow Pull Mode (WaveRT)" on Realtek HD Audio

I use a co3u too but have problems with Win 7 x64. I can't control the mic with the control panel ( reduce loudness) It's always 100% even if I shut it off.
Is there any idea?
Thans in advance
