Pedro's questions

My speakers work correctly, but when I plug in my headphones, they don't work. I am running Ubuntu 10.04.

My audio card is Realtek ALC259 My laptop model is a HP G62t a10em

In another thread someone fixed a similar issue (headphones work, speakers not) folowing this:

sudo vi /etc/modprobe.d/alsa-base.conf (or some other editor instead of Vi) Append the following at the end of the file:

alias snd-card-0 snd-hda-intel options snd-hda-intel model=auto

Reboot

but it doesnt work for me.

Before making and changes to alsa, this was the output:

alsamixer gives me this:

Things I did: followed this HowTo but now no hardware seems to be present (before, there were 2 items listed):

Now, alsamixer gives me this:

alsamixer: relocation error: alsamixer: symbol snd_mixer_get_hctl, version ALSA_0.9 not defined in file libasound.so.2 with link time reference

I guess there was and error in the alsa-driver install so I began reinstalling it.

cd alsa-driver*            //this works fine//
sudo ./configure --with-cards=hda-intel --with-kernel=/usr/src/linux-headers-$(uname -r)   //this works fine//
sudo make    //this doesn't work. see ouput error below//
sudo make install

Final lines of sudo make:

make[1]: Leaving directory `/usr/src/alsa/alsa-driver-1.0.9/acore'

And then sudo make install gives me:

rm -f /lib/modules/0.0.0/misc/snd*.*o /lib/modules/0.0.0/misc/persist.o /lib/modules/0.0.0/misc/isapnp.o

[SOLUTION]

After screwing it all up, someone mentioned why not trying using the packages in Synaptic - so I did. 
I have reinstalled the following packages and rebooter:
-alsa-hda-realtek-ignore-sku-dkms
-alsa-modules-2.6.32-25-generic
-alsa-source
-alsa-utils
-linux-backports-modules-alsa-lucid-generic
-linux-backports-modules-alsa-lucid-generic-pae
-linux-sound-base
-(i think i listed them all)

After rebooting, the audio worked, both in speakers and headphones.
I have no idea which is the package that made my audio work, but it certainly was one of them.

Are the Ralink RT3090 drivers incompatible with Ubuntu 10.10?

I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected.

Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages.

I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.
