ALSA Problems after Feisty Update

I started to get the following problems when running linphone on top of ALSA after my Feisty update.

ALSA lib confmisc.c:1105:(snd_func_refer) Unable to find definition 'defaults.pcm.dmix_format'
ALSA lib conf.c:3500:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:3957:(snd_config_expand) Args evaluate error: No such file or directory
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM dmix:Intel

I thought linphone was the problem, but this had to do with old ALSA configuration files lying around. Removing (or moving) the .asoundrc and .asoundrc.asoundconf files in your home directory, as explained here will do the trick.
