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?

BTW. What's the purpose of the "headphone limiter". Is it some kind of attempt to protect the listeners hearing from excessive volume?
I believe this is an EU regulation. There's something about it mentioned in my Lenovo user manual. (My Lenovo laptop puts-out about 0.75VRMS with a high impedance load. I have not checked it with headphones.)

Thanks for the info Doug. I thought it would something like that.
