OpenSolaris Community&Adoption The courage to innovate

After I install the latest OpenSolaris snv_100, my audio doesn't work,although it appears that it has a driver.But it doesn't work!!!!!!!!!
Here is how I fix this problem.
1. Download the OSS package (http://www.opensound.com/solaris.html)
2. Remove the original audio driver:
-------------------------------------------------
root@sun_ricky:~# modinfo | grep aud
168 fffffffff80f4ca0  29b18 261   1  hdaudio (OSS 4.0 (b1016/200806171344))
216 fffffffff8364000   3a18 242   1  lx_audio (linux audio driver)
225 fffffffff855d000   3988   -   1  audiosup (Audio Device Support %I%)
---------------------------------------------------
Suppose your audio driver name  is " hdaudio "
Input the following command to remove it.
-----------------------------------------------
root@sun_ricky:~# rem_drv hdaudio
-------------------------------------
3. Reboot
4. install OSS package.
--------------------------------
pkgadd -d ./oss-solaris-v4.0-1016-i386.pkg
----------------------------------
5. Test it! Enjoy your music
