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 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?
With the Microsoft High Definition Device driver, I'm reading 444 mVWith the Conexant driver (with headphone limiter enabled), I'm reading 430 mVWith the Conexant driver (with headphone limiter disabled), I'm reading 965 mV
BTW. What's the purpose of the "headphone limiter". Is it some kind of attempt to protect the listeners hearing from excessive volume?
QuoteBTW. 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.)
Take a really close look in the Windows mixer (I'm still using WinXP but there's probably something similar in Win7). Under "options" you'll sometimes find an "advanced options" setting that enables extra stuff like that.
There, see if you have a tab labeled "personalized" or something like that. In that tab I have a checkbox named "Limited output". You need to uncheck this.
I have decided to send my laptop back to Lenovo, since it really should have worked out of the box, or at least with the latest drivers.

I've not had any problems, native audio or Logitech, with audio skipping during network traffic. I've used when I'm docked (cat5) or not (802.11n). That may be a hardware problem.
