Solution to DELLD630 laptop sound card in Ubuntu7.10

I thought Ubuntu 7.10 could make me really use the LINUX system. A sound card that can be recognized automatically under Ubuntu 7.04, but cannot be recognized by Ubuntu 7.10. There is always a little cross under the horn icon, and no mix can be found in the sound.

I tried many solutions: Re-compiled alsa, that is, manually download, manually compiled, and installed. That is not the case, it is completely ineffective, and there is always a cross between the speaker and OSS, after the reboot, it was usable at the time. Although the horn was still a cross, the sound could be released, but it would not work after the restart. In fact, after I restarted it, I unloaded the OSS and restarted it, he can let out the sound again, but he thinks it is too troublesome, and there is no sound system, which is not a perfect solution.

These daily online searches show an article about intel HD on the official WIKI, which seems to be a system problem. Below we provide a lot of solutions, I have my DELL D630 notebook, as he said. After the restart, the sound is normal. So happy.
