Help setting up High Definition Audio Drivers for HP Pavilion dv5-1220ez Notebook

[deomsh]

While reading some old posts I realized we didn't try new functionality of HDA2.DLL version 9.L to select 'Codec index'.

If you like, you can add some lines to HDACFG.INI. New entry [HDA] should look like this:

[HDA]
TSR=TSR Found
PCI_VID=$8086
PCI_DID=$293E
PCI_BUS=$00
PCI_DEVICE=$1B
PCI_FUNCTION=$0
SEARCH=FALSE

BTW first three entries are present already, so you only have to add last FOUR lines. I interpret 'PCI_FUNCTION=$0' as general codec address, but so far I am not aware of any succesfull testing of this feature.

If you want to try: check after reboot if 'Codec index' changes.

I have added the last four line into HDACFG.INI on [HDA], but after a reboot the Codec index is the same ($2).

And what happens if you delete these four lines and only add SEARCH=FALSE to  [HDA_293E8086,3621103C] below the  line PCI_FUNCTION=$0 ?

I have now made the modification in HDAcfg.ini, but after a reboot the Codec index is still $2.

[deomsh]

Maybe I have been on the wrong track and is this function ment to set the PCI-device manually (so the HD-Audio Controller, who communicates with the codec). I did a wide internet-search on 8086:293E, always 00:1b.0 is mentioned, so same as your values.

So best REMOVE lines in HDACFG.INI I suggested above.

The fact that HDALOG.TXT first identifies the right codec on $0 and than switches to codec $2 can also mean a timing problem. Especially because Verbinterface=$1 didn't work on your system.

Timings can be adjusted. I suggest to experiment with the wait-states in steps of 50 (msec), up to 1000 (1 second).

Your current values in HDACFG.INI are:

wait1=$100
wait2=$100
 

Best first go UP, so starting with $150 both.

Check HDALOG.TXT after each reboot too.

I have removed this lines from HDACFG.INI on [HDA]:

PCI_BUS=$00
PCI_DEVICE=$1B
PCI_FUNCTION=$0

and in [HDA_293E8086,3621103C]:

SEARCH=FALSE

 

i tried all timings from 100ms - 1000ms in 50ms steps (and between a reboot). But the Codec index is still $2.

Sorry to hear that.

In my opinion on the side of Watler's HDA-driver nothing can be done further.

But how about the Setup of your laptop?

Are their for instance energy-savings which can be switched off? 

I found some manual of your laptop, but this was not clear for me.

No problem. Before I came to this forum, I never thought that the audio would work on my notebook.
But now, thanks to your help and your skills, it works.
I am happy with the ability to control the volume via HDAICOUT.HDA.
i installed Windows 98 SE witout ACPI-Support (with the parameter /p i).
I had to do this because otherwise I have problems with it.

[deomsh]

Setup /p i is always good. On my 2011 (desktop) motherboard needed too.

But I ment your laptop's BIOS setup. Are there any switches regarding energy savings or MSI?

What does MSI mean? No, I didn't find any settings in the BIOS regarding energy saving.

[deomsh]

Sad.

MSI is Message Signaled Interrupts (PCI-bus mechanism). Personally I do not understand them, but MSI was mentioned in a Linux source in relation to the High Definition Audio Controller.

I have done some reading in the ICH9 datasheet. It seems MSI is disabled by default. Maybe you are lucky if you enable MSI with 'pcipatchB=$6281' (if my reading/ hex-counting of Intel's io-controller-hub-9-datasheet, paragraph 18.1.27 is correct).

As always: at your own risk (if any). Do not forget to study HDALOG.TXT too, if you want to try.

I set the value at pcipatchB in HDAcfg.ini and made a copy of HDALOG.TXT. But after a restart the codec index was still at $2.
There were no changes in HDALOG.TXT

[deomsh]

In that case I think were done. You tried 'pcipatchB=$7900' earlier. You know what to do if you want your headphones back.
