[Please send offers to me personally, not to the list] Hi,
I have a Dell Optiplex 380 (a fairly new model) which is having problems with excessive hiss when recording. Since I've tested without a mic and still got the hiss, I've concluded that it's an ALSA problem. The issue is probably incorrect routing of pins in the ALSA configuration, but I don't know enough about ALSA to figure it out. Any ALSA hackers here who can work out the correct ALSA configuration to eliminate the hiss? I can make a machine available in Sector 7, NOIDA or in Janakpuri, and will pay a reasonable amount for what should be a couple of hours' work. Payment will be on successful configuration -- no money for just trying :) alsa-info.sh output is at the bottom of this e-mail. Please contact me via e-mail or on my mobile (9811066460) if you are interested.
