Ubuntu8.04 install the D630 microphone driver

I recently installed Ubuntu8.04 on my D630. The sound card driver is quite well supported, that is, the built-in microphone is not available. I found a solution on the Internet: First, open the terminal as root, enter the following command in sequence: # echo "amixerset 'capture 'Cap" & gt;/etc/rc. local # The first line of the shutdown-r0 command is to set amixerset 'capture' cap

I recently installed Ubuntu 8.04 for my D630, and the sound card driver supports a lot, that is, the built-in microphone is not available. I found a solution on the Internet:

First, open the terminal as root and enter the following commands in sequence:

# Echo "amixer set 'capture' cap">/etc/rc. local
# Shutdown-r 0

The first line of the command is to write the amixer set 'capture' cap string to/etc/rc. in the local file, output redirection is used here. In fact, you can directly edit the file. Run the following command: gedit/etc/rc. local: Write the string to the end of the file.
