Comment 5 for bug 248503

I just installed Ubuntu 8.10 Intrepid Ibex (Alpha 4) on a Fujitsu Siemens Amilo pro V1000 laptop, which automatically updated itself to kernel 2.6.27-2-generic.

I can confirm that there is sound via PHONES and that I can record both guitar(Input 2/R) and microphone(Input 1/L), with advanced set to either "ON" and "OFF". I haven't tested if MIDI works yet, maybe later.

To reduce the options from the drop downs under Sound Settings, I disabled the internal sound card (onboard Intel AC97 card) by editing /etc/modprobe.d/blacklist:
# turn off internal soundcard
blacklist snd_intel8x0
blacklist snd_ac97_codec
blacklist snd_ac97
(From http://ubuntuforums.org/showpost.php?p=1370551&postcount=8)

In Sound Settings, the dropdown now looks like this, marked with a cross if clicking on Sound works:
x Autodetect
x EDIROL UA-25 USB Audio (ALSA)
x EDIROL UA-25 USB Audio (OSS)
x EDIROL UA-25 USB Audio (OSS)
  ALSA - Advanced Linux Sound Architecture
  OSS - Open Sound System
x PulseAudio Sound Server

Maybe it isn't important, since the sound card seems to work fine, but I tried the sound test for fun, With advanced set to "ON" or "OFF", doesn't matter:
