Internal mic./line in has very low capture volume (hda-intel, acl663)

Did you perform the capture with or without pulseaudio running?

I performed the capture with and without pulseaudio. There was no difference.

Confirm for Ibex and Jaunty. My line in and microphone have very low capture gain. Audio does get recorded, but at a very low volume.

Very similar problem: Dell Inspiron 1525n laptop with built-in digital microphone. Worked fine with 7.10 and 8.04LTS. Upgraded to 8.10 and Skype stopped working. Fiddled with many settings and got it working, but digital mic input is so low, it's almost inaudible. This has been reported by many. Apparently, there was a mic boost feature that is no longer visible in alsamixer. I've tried several workarounds but none have been successful. For the last week, I've been trying Kubuntu 9.04 Alpha 6. It has the same problem.
