First BSD install - previously a gentoo user - HDA_intel help needed

[nagatzul]

Hi

Support for my onboard Intel sound is listed.

I need some help with debugging my sound to get it working.

osstest runs without any errors but no sound comes out.

I'm unfamiliar with the environment, any help appreciated.

Consider me a BSD noob.:confused:

Odds are that multiple devices are in use, but the wrong one is active. Please post
the output of "cat /dev/sndstat" and "mixer" on your system.

FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <USB audio> (rec) default
pcm1: <HDA Realtek ALC885 PCM #0 Analog> (play/rec)
pcm2: <HDA Realtek ALC885 PCM #1 Analog> (play/rec)
pcm3: <HDA Realtek ALC885 PCM #2 Digital> (play/rec)

$ mixer
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer mic is currently set to 75:75

Looks like pcm0 is default. How do I change that?

[kmoore134]

Yep, that looks like the problem. Put this line into /etc/sysctl.conf and restart:

hw.snd.default_unit=1

Does that fix it?

[nagatzul]

Still defaults to pcm1 seemingly.

Any way to do this with a command that doesn't require a restart?

Interesting, it looks like the USB device that was pcm0 dissappeared. Do you have some webcam
or other USB audio device not plugged in now? If so, you may need to set it back to "0" to
get the first analog device.

[nagatzul]

Yes, it turns out I did actually remove my Logitech.

Is there a way to rather assign by device ID which could be more consistent?

[kmoore134]

I did some looking through "man sound" and didn't see a way to do that. If anybody else knows of
a way, feel free to chime in :)

Either way, I think I'll need to investigate doing a sound-config GUI for the 9 series at
some point, so its easy to jump between devices.

[nagatzul]

Thanks for the fast reply.

I tried the sysctl.conf with 0 later 1 and then even 2.

Still not a peep from sound (I know it's on and working because live boot disc has intro sound playing - Sabayon 5 something).

osstest shows me:

I hope that helps.
