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.
