Looking at AlsaMixer as you suggest, I definitely see the HDA Intel<br>
card. Master and PCM have volume levels; Headphone and Speaker show up<br>
but do not have mixer values.<br></blockquote><div>...</div><blockquote class="gmail_quote" style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0.8ex; border-left-width: 1px; border-left-color: rgb(204, 204, 204); border-left-style: solid; padding-left: 1ex; ">
