[LAU] Problems with Lenovo X61

I have a Lenovo X61 I bought second hand hoping to use it for some audio work. But when using a USB output device (a MobilePRE M-Audio through jackd) the volume is very low. Too low to drive my amplifiers or even my headphones. In exactly the same system I use an Acer laptop with no problems at all. I cannot find any mixer controls that help. Does anyone out there have a similar problem and know if it can be solved? Where I should start? cheers Worik -- Why is the legal status of chardonnay different to that of cannabis? root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand) I voted for love
