<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br />external converters are invisible to ALSA, just as they are to CoreAudio or any other audio API. they exist on the "far side" of the device being controlled by the driver, and only exist as far as the driver is concerned in an indirect sense - they might control word clock-driven sample rate, for example. <br /></p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Wow that's a bummer. No external converters?</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Is there no mechanism to set the converter levels other than hard-coded hacks?</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Could this be solved be someone writing a userspace app to do it,</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> or is this more of a core ALSA problem which would need wider fixing?</p>
