I would like your input please. I’m using an HP DV7 laptop and the sound works under Opensuse 11.2 but without base. I have therefore updated ALSA to version 1.0.22.1 to make use of the introduced base switch for DV7 (ALSA changelog here)
I have tried these ALSA options but without any change / improvement to the base sound.
options snd-hda-intel=hp-dv5 and also hp-dv7 and hp_dv7
options snd-hda-intel enable_msi=1
Any ideas?
The second line stops the sound from “stuttering” but the first seem to have no effect.
Thanks for pointing that out :shame:
Having now corrected the syntax which has made no difference to the sound quality, I’m still at a loss as how to use the base switch introduced in the latest ALSA. Any ideas?

The bass speaker is controlled via GPIO5.
please post … providing in your post the following information:
provide the URLs (of a summary webpage) that are created by running the diagnostic script noted here: SDB:AudioTroubleshooting - openSUSE - Script to run to obtain detailed information. On openSUSE-11.1 and newer that will ask you to run the script /usr/sbin/alsa-info.sh and after the script finishes it will give you a URL to pass to the support personnel. Please post here the output URL. Just the URL. You may need to run that script twice (the first time with root permissions to update in the /usr/sbin directory, and the second time to get the URL).

Thanks. You have some things wrong. First hp-dv7. There is no such model option. You can’t just make these up by putting your PC model in there and expect it to work. These models are assigned by the alsa developers.
You have probably made everything much worse by what has been done, and we need to try to undo this.
First, I note your PC has a IDT 92HD71B7X (from the script you ran). The model options for that from the HD-Audio-Models.txt file are:
STAC92HD71B*
============
ref Reference board
dell-m4-1 Dell desktops
dell-m4-2 Dell desktops
dell-m4-3 Dell desktops
hp-m4 HP mini 1000
hp-dv5 HP dv series
hp-hdx HP HDX series
hp-dv4-1222nr HP dv4-1222nr (with LED support)
auto
there is no hp-dv7 in that list.
So change hp-dv7 in that /etc/modprobe.d/50-sound.conf file with either hp-dv5 or one of the other options in the list I quoted above. I recommend hp-dv5. Only after you do the update below, should you try something other than hp-dv5.
Next, alsa-driver-kmp-desktop-1.0.22.1.20100409_2.6.31.5_0.1-3.1.x86_64 does not appear to have installed properly. Delete it. And then re-install it but this time go for the latest version: alsa-driver-kmp-desktop-1.0.22.1.20100411_2.6.31.12_0.2-2.1.x86_64.rpm
