This is exasperating. After re-building alsa sound support as kernel |
14 |
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. |
16 |
With mic-boost turned up, I can hear myself echoing when I talk into the |
17 |
internal mic or into an external mic. Turn up the boost high enough, |
18 |
and the external mic generates a mean high-ptched feedback squeal, |
19 |
unless I also plug in headphones. |

So the hardware is working now, *BUT I STILL CAN'T RECORD THE BLEEPING |
22 |
THING*. When I try "ffmpeg -f oss -i /dev/dsp audio.wav" it thinks it's |
23 |
recording, but the output file is only hiss. Ditto for the command |
24 |
"ffmpeg -f alsa -i plughw:0,0 audio.wav". |

I notice that I have a file named /etc/modprobe.d/alsa.conf but no |
27 |
alsa-base.conf file. Should I rename it? |
