[HP EliteBook 2730p, Analog Devices AD1984A, Green Speaker, Internal] No sound at all, No mic at all

[g]

I am running Ubuntu 11.04 (amd64) on a HP 2730p. There is no audio output or capture. I have unmuted everything with alsamixer. The hardware appears to be detected and running. Here is my alsa debugging output:

Modifying alsa-base.conf doesn't appear to do anything.

Just to repeat:

hardware is detected and modules loaded.
everything unmuted via alsamixer.

There is no sound either on speakers or headphones and no mic capture.

[g (ennui-bz)]

fixed by adding /etc/modprobe.d/sound.conf with the following:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=laptop enable_msi=1 single_cmd=1 index=0

[Daniel T Chen (crimsun)]

Hmm, that seems a rather suboptimal workaround. Would you please try
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules without any
modprobe options to snd-hda-intel?

[g (ennui-bz)]

i was wrong about it being fixed.

adding options to sound.conf only activates the sound after a suspend/awake cycle. But then, it doesn't detect the headphone jack. I tried installing 10.04 LTS and it still behaved this way with kernel 2.6.32

installing: linux-alsa-driver-modules-$(uname -r) for either 11.04 or 10.04 didn't change anything.
