No Sound - snd_hda.ko - HDA Realtek ALC888 PCM - PC-BSD Forums

silkie · #1 12-24-2010, 01:31 AM

I'm a FreeBSD user and I'm investigating PC-BSD. Was happy until I found my sound card wasn't working and the hardware has been fine in FreeBSD (8.0-RELEASE-p6)

I finished a fresh install of PC-BSD

Code:

I have even toggled hw.snd.default_unit in /etc/sysctl.conf between digital and analog to no avail. Was analog in freebsd, I guess I grasping at straws.

I'm out of ideas!

I even double checked the speaker cable to the PC! The sound works fine when I boot by FreeBSD disk and simply specify snd_hda_load="YES" in loader.conf.

I wish to migrate to PC-BSD so any help would be awesome! Everything checks out I simply have no sound.

audio works fine in FreeBSD on XFCE.

only difference I can spot is oss_enable="YES" is in /etc/rc.conf

reflected in kldstat output

Code:

 6    1 0xffffffff80ea3000 23ed0    snd_hda.ko
 7    2 0xffffffff80ec7000 75708    sound.ko
23    2 0xffffffff81f5b000 82dce    osscore.ko
24    1 0xffffffff81fde000 231fc     oss_hdaudio.ko

sndstat looks better also and note it's the same driver!

Code:

pcm0: <HDA Realtek ALC888 PCM #0 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)

pcm3: <HDA Realtek ALC888 PCM #3 Digital> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)

no mixer availble in my FreeBSD install

osstest looks odd but as it works I'm not sure about the validity of this check

Code:

NOTICE! You don't have any audio devices available.
        It looks like your audio hardware was not recognized
        by OSS.
	       
        If you have installed OSS just a moment ago then it may be necessary to.
        to rebot the system before trying to use the device(s).

I'm thinking is is definietly some PC-BSD/KDE specific bug. Will report back on the update rc.conf on my PC-BSD install.

Ta,
Jon

That sounds like you are using the "oss" port from "audio/oss/"

Is that the case? If so, you can try adding oss_enable="YES" to start it on
PC-BSD as well, just be sure oss is installed from ports first

I have the same problem in 8.2.
Any solutions?

Edit: Never mind, i unplugged my webcam and wacom tablet and now the audio works with 2 channels only.

daemonwritus · #5 07-06-2011, 05:04 PM

Was having the same problem. Somebody suggested

#sysctl hw.snd.default_unit=1

And it works. They talk about it in this forum:
http://www.daemonforums.org/showthread.php?t=5328

I don't even know what this command does being a noob and all. But thought this might be helpful to some.

I only wanted to share how I was able to solve my sound problem thanks to this forum.

I installed PCBSD 8.2, but noticed that the sound (phonon) did not work. Searching through this forum I found that I could solve my problem adding this line to the file /boot/loader.conf:

Quote:

hw.snd.default_unit="1"

I did that, and the problem was solved.
But thanks to this forum I also learned that there existed a file named /etc/sysctl.conf. I look at that file and found the following lines:

Quote:

# Autodetect the most recent sound card. Uncomment for Digital output / USB
#hw.snd.default_unit=1

So I decided to let file /boot/loader.conf as it was at the beginning (without hw.snd.default_unit="1"), and instead to uncomment the mentioned line in /etc/sysctl.conf.

This also solved my problem, and I think that this second option is better. But it seems that for other people (http://www.daemonforums.org/showthread.php?t=5328 the only working solution is the first.
