View Full Version : [ubuntu] Alsa problems with Dell (no Sound output at headphone jack)

November 4th, 2010, 11:02 AM
I bought a new laptop (dell Precision M4500) and installed Ubuntu on it. But as mentioned above I can't get the sound to work properly.
In the german Wiki (http://wiki.ubuntuusers.de/Soundkarten_konfigurieren/HDA?redirect=no) it says to look up my codec in ALSA-Configuration.txt or HD-Audio-Models.txt but I can't find it there.
I have tried different entries (snd-hda-intel model=xxx) for various dell laptops in the alsa-base.conf but none of them seem to work.

cat /proc/asound/cards

0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xe9660000 irq 48
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xe3080000 irq 16

head -n 1 /proc/asound/card0/codec*

Codec: IDT 92HD81B1C5It would be really nice if somebody could help me with this because I don't know what else to try and I can't use Ubuntu like this.
