do you mean audio work with the emulated hda sound card before you upgrade ? or just other emulated sound card work before upgrade since the emulated hda sound card is quite new compared with emulated AC97 sound card ?

Since upgrading to Ubuntu 13.10 audio no longer works in KVM.
 Checking SYSLOG I found this error being logged:

Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21 Analog] alsa-source.c: ALSA woke us up to read new data from the device, but there was actually nothing to read!
 Oct 31 15:32:31 bmullan-virtual-machine pulseaudio[1814]: [alsa-source-ID 21 Analog] alsa-source.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
