After upgrading to 13.04 from 12.10 Lubuntu lost audio playback after unplugging usb soundcard (Polycom) and plugging it back in. Volume control was gray and leading to pulseaudio mixer (not installed) so I uninstalled the pulseaudio package. I also removed and reinstalled the alsa-base package. After restart I have the alsamixer back everything seemingly as usual(volume 100%, unmute) but every sound program gets me errors no matter what device I select.
aplay -L:
null

Following gets same result with both devices. aplay -vv -D front:CARD=NVidia,DEV=0 "Release the Pressure.wav":
Playing WAVE 'Release the Pressure.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

Guayadeque mp3 playback:

Audacious:
ALSA error: snd_mixer_attach failed: No such file or directory.
ALSA error: snd_pcm_open failed: No such device.
So How do I fix my audio?
UPDATE: I removed the usb soundcard and got rid of all alsa config. Everything is working as before the install but it sure feels fragile.
