Intel ICH8 (AD1984) - No Sound under ALSA 1.0.16 2008-03-25

Description

No hangs, but no sound, either.

System is a ThinkPad? T61 with onboard AD1984 HDA. Boot is normal (ACPI 3.05: /SMP /APIC; GenMAC 2.20), but no sound.

Previous HDA versions (which actually allowed booting without a Trap E) would lock the system upon attempting to play sounds.

Replying to psmedley:

Please also try with Uniaud 1.9.2

Paul, I skipped ahead to try 1.9.3 and then back to 1.9.2 (rolled back uni16 to 114RC5). No sound (lockup after a few moments w/1.9.3). I will try the uni16 debug you suggested and update logs next week.

Thanks!

I don't think that ICH8 is supported as yet by ALSA. (I would like to have sound enabled for an R61i with the ICH8 Audio controller 0x284B.)

Can't speak to the website, but there are plenty of ich8 references in the source

Hi Lewis - this problem is still present with latest builds? This is the problem where you need to use unimix to change mixer controls to get volume?

Apologies for the long silence, Paul (no pun intended)...

This afternoon, I upgraded the RC5 install on the T61 to RC6a. Elsewhere, I had reported (discussed) boot difficulties under ACPI with /APIC enabled (this was with 1.9.12). I had the same experience here until I upgraded ACPI to 3.15. The system then booted with /APIC.

System sounds work under 1.9.14 / ACPI 3.15 (/SMP /APIC). Youtube videos which were playable did play - and smoothly. I was able to switch from one playing video to another, though I did hang Firefox once in the process (could have been a bad Flash stream, as that one didn't want to play, anyway).

I still had to set the volume levels manually:

unimix.exe -id3 -cnt0 -val1 unimix.exe -id3 -cnt1 -val1 unimix.exe -id27 -val33

As expected, no hardware volume control (I should be able to get the buttons to work with an ACPI-aware tool, however).

Let's close this ticket. Sound works.
