The amp circuit on some HD audio chips (Nvidia) is notorious for low power audio recording even with 20dB power boost. A powered microphone is required to do recording as The on board preamp circuit is insufficient. Venu can you borrow a powered Microphone and try test again ? Otehr option is to run Windows and see if it works w/o powered microphone.
Let's back up a bit. Does audioplay work using the sample file say space.au ok on the internal speaker ? I want to make sure that the audio codec is working at least for output. Also, are you sure the mic jack is in the correct slot (what color is the inside of the jack port red or green or white ?) -Sean also check test is to run windows on same platformOn 2008年10月17日 18:16, Garrett D'Amore wrote: > Venu Chennupati wrote: >> Hi Sean, >> >> I have Intel HD audio controller(0x8086, 0x811b), by trying the >> suggested >> commands I am not able to all kinds of sounds.
