Recording problem
Sorry. How should I start installing the v4 kernel? I just downloaded
and did "sudo dpkg -i *.deb". But I got "errors encountered installing..
(the kernel)".
Do I have to do " sudo dpkg -r --force-all (something here)" first? Also
what will happen to the original -26 kernel?

Thanks for this. I tried it with your Hdmi.conf from v4. I could boot up
to the login screen. After seeing the login GUI screen for a few
seconds, the system just freezes (no longer responds to mouse and

Hi Hui Wang. I'm on a -28 kernel. Did what you said to install the -26
v4 kernel. As usual, comment out "options snd-intel-dspcfg
dsp_driver=1". Use my Hdmi.conf. When I rebooted with the -26 v4 kernel,
I got stuck at a black screen again. But this time, I decided to try it
a couple of times. It
Forgot to say that I see "Dummy output" in pavucontrol, and there is no
sound.
