Comment 15 for bug 1246929

seem get a poll from the emulated ICH controller just at the time of starting capture 0.052 , there is no data to read of course

( 0.052| 0.000) E: [alsa-source-Intel ICH] alsa-source.c: Most likely this is a bug in the ALSA driver 'snd_intel8x0'. Please report this issue to the ALSA developers.
