> Hi all,

> Michael mentioned getting noise with PortAudio and I just experienced

> PortAudio device 0
>   /dev/dsp
>   Maximum channels in:     16
>   Maximum channels out:    16
>   Default sample rate:  44100.000
> PortAudio device 1
>   Intel 82801CA-ICH3
>   Maximum channels in:      2
>   Maximum channels out:     2
>   Default sample rate:  44100.000
