After re-building alsa sound support as kernel modules, rather than built into the kernel, I see some improvement. When I blow into the internal mic I hear it from the laptop speakers. With mic-boost turned up, I can hear myself echoing when I talk into the internal mic or into an external mic. Turn up the boost high enough, and the external mic generates a mean high-ptched feedback squeal, unless I also plug in headphones. So the hardware is working now, *BUT I STILL CAN'T RECORD THE BLEEPING THING*. When I try "ffmpeg -f oss -i /dev/dsp audio.wav" it thinks it's recording, but the output file is only hiss. Ditto for the command "ffmpeg -f alsa -i plughw:0,0 audio.wav". I notice that I have a file named /etc/modprobe.d/alsa.conf but no alsa-base.conf file. Should I rename it? -- Walter Dnes
