Jean-Pierre, thank you for the suggestions.
Unfortunately, I have tried the boot options irqpoll, noapic with no luck. Additionally, I installed mplayer and it produced no sound through the speakers. Finally, I added option snd-hda-intel model=hp-m4 and hp-m5 in alsa-base with no luck.
Try "model=hp-dv5". After changing the model parameter, reboot once, and check whether the module parameters are really set properly via /sys/modules/snd_hda_intel/parameters/model.
Double-check the mixer elements all adjusted and unmuted. If it still doesn't work, post with the attachment of alsa-info.sh (with --no-upload option) output with model=hp-dv5.

The whole time, if I plugged my headphones in, they would continue to work.
I did just notice one more thing. Although Linux shows my sounds as volume all the way up, and not muted. The speaker mute button on the laptop appears in red with the mute symbol (meaning it's muted). Any idea why that is? Possible that it's the wrong driver? This is bizarre as the headhpones work fine.
Any ideas?

Hi,
Hi all, I have an HP DV4 1155-SE, I've been unable to get sound working through the speakers, although it does work through the headhpones. I ran alsa-.upgrade which downloaded compiled, and installed 1.0.19 - still no luck.
I have the same IDT codec 92HD71B7X on another HP DV4 model, and I have tracked the problem to be the kernel configuring IRQ 22 through the APIC, but interrupts triggerring IRQ 20 (on kernel 2.6.27 and alsa 1.0.19). It would be interesting if you could confirm this by analyzing /proc/interrupts.
The workarounds I know of are :
- adding irqpoll to the boot options,
- or adding noapic to the boot options,
- using mplayer to play music.
There are with option "snd-hda-intel model=hp-m4" (this option is for HP DV5/DV7, but HP DV4 is probably different)
I have not enough knowledge to tell where the problem lies : kernel, apic, alsa.

I ran alsa-info, output here:

I filed a bug, here: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4374
Any ideas?
