Question about HP Pavilion dv4000 Notebook
I have a hp dv4, . When i turn on the computer , the mute light is on and i can´t turn it off, but in the laptop´s screen appears the sound icon and it displays that the computer´s sound is working perfectly and mute is turned off. To solve the problem I have to restart the computer 3 or 2 times, so that the mute light on my laptop can be turned off and on, but i keep getting this problem as I say average 3 times a week.
A couple updates will solve this issue of a non-responsive mute button (and perhaps related problems).
Go to www.hp.com. Click on the support and drivers tab and locate your model and operating system.
Download the latest audio driver (near the top), and also the latest file for the "quick launch buttons" (your touch-sensitive controls) under keyboard, mouse and input devices.
Try the audio codec first. Both files are self-installing. Just double click and restart when prompted.

... the alsa developers have a solution for this issue:
When you boot you get no sound from your internal laptop speakers though you do get sound from the headphone jack.
The cause, according to some alsa developers, is an incorrect 'pin' assignment (in the BIOS, perhaps) whereby sound output meant for the internal speakers gets routed to the wrong place.
If you have an HP dv4, dv5, and perhaps a dv7 model series laptop, you may have this issue.
The latest alsa-driver snapshot provides a fix for this issue. I'm listening to a Keith Jarrett jazz cd right now through the internal speakers of my HP Pavilion dv4 1225 laptop after downloading, compiling, and installing the latest snapshot. You can get it here:
After downloading and gzip/tarring the files, you'll need sudo privileges to:
Code: #> ./configure --enable-dynamic-minors
#> sudo make install-modules
#> sudo vim /etc/modprobe.d/alsa-base
[add 'options snd_hda_intel model=hp-dv5' sans quotes to the bottom of the file, even if you have a dv4, etc.]
#> sudo reboot After restart, you should have sound from the laptop speakers.
If you do not, you should consider the alsa developers your best resource. They have some tools you can use to discover what's happening and since they write the code that goes into the kernel for the sound drivers, they can hopefully fix your problem. Just go to the alsa web site and find the alsa-devel email list and join up.
NOTE: this does not require a kernel build I post this to the ubuntu forum with the permission of several of the alsa developers I've been working with.

Check in system information ...look in conflicts/sharing if you see your sound device there see what other device is sharing irq..goto to device manager and select either device and change i.o. values(input/output)
press ok close programs and restart

SOURCE: NO SOUND ON A NEW HP DV4
sounds like it's a physical problem not software, but to be sure i would update the audio drivers and see if that helps.
go here and pick your system and follow the steps to get any new drivers and install and see what happens.
please, Let me know :)
