Bug 148488

Summary:	Headphone won't work on NVidia MCP78 High Definition Audio Controller
Product:	Base System	Reporter:	snthibaud
Component:	amd64	Assignee:	freebsd-amd64 (Nobody) <amd64>
Status:	Closed FIXED
Severity:	Affects Only Me

Hardware:	Any
OS:	Any

Description snthibaud 2010-07-11 01:40:05 UTC

The headphone output doesn't provide a signal nomatter what sliders I move in KMix.

My soundcard gets detected as follows:

hdac0: HDA Driver Revision: 20090624_0136
hdac0: [ITHREAD]
hdac0: HDA Codec #0: Conexant CX20561 (Hermosa)
hdac0: HDA Codec #3: NVidia MCP78 HDMI
pcm0: <HDA Conexant CX20561 (Hermosa) PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA Conexant CX20561 (Hermosa) PCM #1 Analog> at cad 0 nid 1 on hdac0
pcm2: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

I have a stereo headphone output on this laptop and a microphone input. Please note that I do hear sound over the built-in speakers and plugging in a headphone doesn't change that (sound isn't muted either). Perhaps some kind of jack-sensing doesn't work

How-To-Repeat: Boot Kde4, play sound.

Difficult to say for sure without seeing verbose dmesg, but may be that
headphones and microphone input just configured as separate device pcm1.
You may try to set sysctl hw.snd.default_unit=1 to use that device by
default. In any way make sure to read snd_hda man page and analyze
driver's verbose output.

Thanks for your quick response. To be honest I uninstalled PC-BSD already (=

PC-BSD seems so much more stable than kubuntu, not to mention the terrific =

license!). Can these sound tweaks be tested with the live-boot-thing of PC-=

or is a reboot needed?


Sincerely,

Default sound device can be set on-the-fly via sysctl.
