Does it fix the problem as well? Sadly, no. Now there is no headphone output at all.

Kind of no. As I said, there is no headphone output, BUT the laptop built-in speakers ARE muted when the headphones plugged in. >> And "Independent HP" has absolutely no effect, which is probably as it >> should be on this laptop. > > With the independent HP turned on, there should be no output to the > headphone through the normal PCM.

I misunderstood (miscounted?) the playback PCMs: this card has three (VT1802 Analog, VT1802 Alt Analog and ID 2806 Digital), the last one being HDMI (just deconfigured, while I was trying to figure the headphones out). The first two named appropriately (if one looks at them), and when tried (hw:0,2. Strangely, there is no hw:0,1) it indeed works (with the revised patch. Not with this one). Regards, Alex
