I noticed the high-pass, but came to acceptable results using
alsamixer's bass-boost options. My main concern is with the distortion
in the mids to highs. As far as I understand, the above mentioned
postings only cover the high-pass problem. But I certainly don't
understand all the technical stuff.

Does anyone else experience distortion?
