Bug Description

I have a logitech USB headset 250 and it's the only audio device on my system (onboard is totally disabled in bios) . It worked perfectly in Dapper LTS. Upon installing feisty it would no longer work. The problem seems to reside in Alsa and I confirmed it by installing edgy and updating alsa (which recreated the problem). I followed the workaround from https://bugs.launchpad.net/bugs/101920
to create an .asoundrc in my home folder. That fixed the audio but when I type alsamixer into a terminal I get: alsamixer: function snd_ctl_open failed for default: No such device and quite a few programs that use audio such as mplayer and acidrip will still fail to find the audio device and crash. The problem seems to be that alsa is pointing to a non-existent device for use as the default audio.
ps: I have noticed a lot of other people having this problem but no available answer resolves it.

this is my .asoundrc:

pcm.!default {
type plug
slave.pcm "combined"
}

pcm.combined {
type asym
playback.pcm "playback"
capture.pcm "hw:1,0"
}

pcm.playback {
type dmix
ipc_key 1024
slave {
pcm "hw:1,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}

ctl.dmixer {
type hw
card 1
}pcm.!default {
type plug
slave.pcm "combined"
}

pcm.combined {
type asym
playback.pcm "playback"
capture.pcm "hw:1,0"
}

pcm.playback {
type dmix
ipc_key 1024
slave {
pcm "hw:1,0"
period_time 0
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}

ctl.dmixer {
type hw
card 1
}

output from amixer:
amixer: Mixer attach default error: No such device

however amixer -c1 returns:

What's the package name of alsa do you have updated ?

Have you tried this on Feisty ?

Alsa is at 1.0.13 and the package name is alsa-base at version 1.0.13-3ubuntu1. I'm running feisty and this is the latest version in the repositories. This probably also effects upstream.

While this bug report and bug #101920 both refer to the same HARDWARE they are entirely different problems.

I am willing to test alsa 1.0.14 to see if that fixes the problem. Which is the best method of replacing alsa 1.0.13 with 1.0.14 on ubuntu fiesty i386?

If everything starts working again (like in dapper) it will prove that an update package to 1.0.14 is all that's needed.
