I just tried a newer kernel and noticed that I didn't have any sound anymore. Normally I hear all kind of interference in the earphones and now it stops when asus_laptop gets loaded. I can play things, but nothing comes out. It feels like it disables something it shouldn't. I did a bisect with this as result: d99b577c729c4a29679fb1f605f9ccace154e0e5 is the first bad commit commit d99b577c729c4a29679fb1f605f9ccace154e0e5 Author: Corentin Chary <corentin.chary@gmail.com> Date: Fri Jan 22 21:20:57 2010 +0100 asus-laptop: stop using ASUS_HANDLE and use relative methods instead Stop using ASUS_HANDLE because most of the time it is not needed. This macro was introduced to display_get and lcd_switch which are not part of the interface provided by Asus, and are scheduled for removal.

If I add the parameter "wlan_status=-1" it audio doesn't get disabled. This laptop doesn't have on board wireless. Kurt
Wow, that seems really wrong. Can you send me the output of acpidump | gzip ? Thanks,
Created attachment 42082 [details] acpi dump During boot I see the following messages: [ 11.357632] asus_laptop: Asus Laptop Support version 0.42 [ 11.372321] asus_laptop: Error calling CWAP(1) [ 11.374462] asus_laptop: L84F model detected [ 11.385042] input: Asus Laptop extra buttons as /devices/platform/asus_laptop/input/input8 [ 11.393055] Registered led device: asus::mail The dump file seems to say L1400B, which might make more sense for the model number.
Hum, the DSDT provides a WLED method, traditionally used to control the wireless device/led, but that one control the sound card, great ! For L84F it's the string returned by the INIT() method. Does the mail led works ? (/sys/class/leds/asus::mail/). Is there any BIOS updates for your model ? because your dsdt seems really broken.
I can toggle the led, so that works perfectly. I can't find any BIOS version online. It's a rather old laptop.
Do you have a suggestion on how to fix this?
Sorry for the delay, I did not see your previous answer. As a short term workaround, you should use "wlan_status=-1". The only thing I can do is probably blacklisting this model, could you send me the output of dmidecode ? Thanks,

So is there something else I can do?
Sorry fort the delay, again.... Could you try that patch ? http://git.iksaif.net/?p=acpi4asus.git;a=commit;h=6ffb6745a7d115c2f1f23351db97ccff98d66ca7 Thanks,
That patch fixes my problem. Testing some more I found out that the audio isn't completely disabled, it's just very low volume, like it's muted or something.
