I have a Lenovo W520 with 2nd gen i7, 8GB RAM, running Windows 7 64 bit, and foobar2000. The audio skips during network activity when using the Conexant audio driver, but it doesn't have this problem with the Microsoft High Definition Device driver. This is even when the buffer in foobar2000 is set to 1500 ms.

The problem with the Microsoft driver, is the volume is limited (maybe 5 dB lower) than the Conexant driver. This is unacceptable when driving the Sennheiser HD 600 headphones with ReplayGain enabled, especially during quite passages. Is it possible to bump up the volume of the system when using the Microsoft driver?

So long as your playback is via foobar2000, you can boost the preamp gain:

The foobar2000 preamp gain won't help very much when the track peak is close to 1. Money For Nothing, from the Dire Straits CD Brothers In Arms (Track gain: +2.74 dB, Track peak: 1), won't be boosted by the preamp gain at all.

I used to worry about clipping prevention too. Now, for me, a major mismatch in volume is worse than mild distortion to a noise-like transient peak, so I use Apply Gain without using clipping prevention in foobar2000. I then use the Advanced Limiter DSP which will look ahead and limit only peaks that would exceed 1.0 (full scale). So long as my preamp level is sane, that sounds great to me.
