My audio codec is Conexant CX20561 (Hermosa) (haven't been able to find
anything about 'Hermosa' on the Wiki).
I'd like to be able to do a few things which I have not been able to do with
tutorials I found on the web:
- Whenever I plug in headphones, HDMI output is muted and headphones are
- Right now, the way I do this is by manually editing /etc/asound.conf to
have the following (commented out makes headphones work, not commented makes
HDMI work without any headphone/laptop speaker output)
where 3 is my HDMI (IEC958 2; no idea what IEC958 1 is for) output. So I have
a switcher script that does the commenting and uncommenting. Would be nice if
this could be automatic (even if alsa had to run such a script on detecting
- Route audio output (PCM) to input (for mixer recording) (Intel HDA cannot do
this apparently by default (thanks DRM), needs some hacking around?)
Information from alsa-info.sh: http://www.alsa-
Are my model options correct?
And if it's important to know, I build ALSA in-kernel. Is this not
recommended? I know at the very least it makes it such that I have to reboot
to make any new options to take effect.
