Skype finally works in 64 bit Ubuntu 8.10

When upgrading from hardy to intrepid, I decided to try out the 64 bit operating system.

Ubuntu really rocks. Even Skype now has the 64 bit version, to install it, first add the Medibuntu to the source list:

sudo wget http://www.medibuntu.org/sources.list.d/intrepid.list -O /etc/apt/sources.list.d/medibuntu.list
sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update

then:
sudo apt-get install libdvdcss2 w64codecs skype

Yes, that's right, even w64codecs is available...

But after that, when I tried to open skype to make a test call, it says: problem with audio playback. I restart everything and still nothing. I tried it in the terminal, it says:

ALSA lib ../../../src/pcm/pcm.c:2156snd_pcm_open_conf) Cannot open shared library /usr/lib32/alsa-lib/libasound_module_pcm_bluetooth.so

I googled a little, and tried to get the 32 bit lib by:

sudo getlibs -p bluez-alsa

This obtained the lib successfully, but I have another error:

ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES failed : Input/output error(5)
ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES failed : Input/output error(5)

ALSA lib pcm_bluetooth.c:1619:(bluetooth_init) BT_GETCAPABILITIES failed : Input/output error(5)

Then I got really desperate...

But finally, I changed the options of sound devices, change the Sound In etc from default to HDA Intel, everything works!
