Hello everybody, Recently I have installed Fedora 10 on my Compaq CQ45 laptop. But unfortunately there was no sound from the laptop speakers even though the headphones worked perfectly. I did some google search but it didn't helped. Later, on a discussion at #alsa(freenode.net), one of the IRC member(nickname: copper) gave some clue and finally found that I have to upgrade the alsa driver and pass the model id(dell-m4-1) as a parameter in modprobe.conf. Here are the results generated by alsa-info.sh before and after upgrading to the latest alsa(1.0.18a).

The option I have passed to /etc/modprobe.conf/alsa-base is : options snd-hda-intel model=dell-m4-1
After reboot, I was able to hear sound from laptop speakers.
Thanks for reporting.
Could you try the latest snapshot below and check whether the problem still exists and model=dell-m4-1 works? ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
If the model option is still needed, I'll add the quirk entry.
Note that you should reboot after changing the model option for STAC/IDT codec, just to be sure. When a model option is specified, the driver may override the BIOS setting.
thanks,
Takashi
Thanks for your consideration. Right now I don't have access to my laptop. I wills surely test it this weekend and let you know the status.
