Updating my sound
I actually found out that my Realtek audio codec was ALC269 by typing The full list of models is available in in the subdirectory /alsa-kernel/Documentation/ of the alsa-driver-1.0.14 directory you created.
You may need to right click on the volume control applet in your gnome-panel and go to the preferences and change the device to the one called Alsa Mixer.That event window was opened by the Win XP soundcard driver when I plugged in the microphone.I then booted ubuntu 7.04 with alsa-driver-1.0.15-rc3 and used alsamixer to make the following changes: 93.Eventually, I pressed Esc to end alsamixer and save my changes.If your boot hangs on loading the module for snd-hda-intel, try disabling the card in your BIOS.It is called "HD Audio Controller", "Azalia Audio" or similar.
Then try solving the problem using the instructions below.
I'd like to add an example to clarify: my mic did not work under Ubuntu (whereas playback did and the mic itself worked under Vista).
The same applies to the gnome volume control program.
No mic working, rest OK: Firstly, check if muting one of two microphone channels makes a difference.
This is usually front right, but on some occasions also works with muting front left.
Follow this hyperlink to section "Increasing very low microphone input" to see how to do it https://help.ubuntu.com/community/Sound Troubleshooting#Line_Input.2BAC8-Microphone_Troubleshooting After installing and configuring the Intel-Sigma Tel STAC 9205 soundcard in my DELL Latitutde D630 as described above, I could use xmms to play sound on this machines. To make the mic work as well, I booted Win XP on the same machine, plugged the microphone in and selected Microphone instead of the menu items "Line-In" or "No action" in the Intel-Sigma Tel event window.
