Sound Not Working--Duplicate Sound Devices

[FitzLT]

On the livedvd for PCBSD 8.0Beta, my laptop had sound. After the install, I did not have sound. When I typed "dmesg | grep pcm" in konsole, it shows there are two sets of the same sound card according to PCBSD. When I open KMixer, I have two set of "OSS Audio" tabs available--both with "Front" and "PCM" slide bars. I can individually set the settings for each "OSS Audio" tab, but no sound. Is there a way I can get PCBSD to recognize only one sound card instead of duplicates? Thank you for any help I receive.

/home/lawrence(27)% dmesg | grep pcm
pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0
pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

I have the same problem..do you solve this problem???

[FitzLT]

Unfortunately, I have not. I'm not sure how/what to remove to prevent PCBSD from seeing duplicate soundcards. I'll keep googling and post back when/if I find something.

I heard that some ppl have had success with by disabling sound completely from /boot/loader.conf

oss_enable=NO
sound_enable=NO

and so forth... disable all..

because while booting the rc.conf is mostly loading PCBSD's Sound script and then loading the right kernel modules.

therefore enable this rcvar in /etc/rc.conf
# snddetect
snddetect_enable=YES

give feedback

[FitzLT]

I apologize for responding so late--I have been offline for a little while. I was not able to find "oss_enable" or "sound_enable" in my /boot/loader.conf file. There was this:

# Load sound-support
sound_load="YES"
snd_uaudio_load="YES"

I changed those options to "NO", then navigated to /etc/rc.conf. Here I found this:

# Enable sound-support
snddetect_enable="YES"
mixer_enable="YES"

I kept these at "YES", saved both files and rebooted. I should mention that I am now using the Release Candidate. After logging in, I still do not have sound and mixer is still showing duplicate of "OSS-audio". In fact, one more was added. See below:

root@pcbsd-2800# dmesg | grep pcm
pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0
pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0
pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

I have been trying to log onto Trac to post a bug report, but I need to verify my email address and I have not been receiving the verification email. I have already checked to see if the correct email address is in my profile. Any help would be appreciated.

I wanted to show you all part of the output from 'dmesg':

hdac0: <Intel 82801I High Definition Audio Controller> mem 0xf2500000-0xf2503fff irq 22 at device 27.0 on pci0

pcm0: <HDA Realtek ALC268 PCM #0 Analog> at cad 0 nid 1 on hdac0
pcm1: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 3 nid 1 on hdac0

Still have not found a solution yet. Will keep trying...

So it's loading 2 sound cards, a Realet and NVidia?
Does your machine actually have 2 sound cards?

What does the following command output?
(May have to be run as root)

kldstat

This will display all modules currently being used by the kernel.
I am no expert but once I had similar issues with a network card that was being misdetected. It turned out the 2 modules were fighting over the same component and once I unloaded one of them it started to work properly.
Type:

kldunload

to unload a module.

I'm not supposed to have two sound cards--I'm not sure why the Nvidia card is being detected as a sound card. It is an Nvidia GeForce 9600M GT and does not have any sound capabilities that I know of.

When I type "kldstat", I get this:

I only see the one sound driver loaded, so I'm not sure how to stop the OS from seeing Nvidia as a sound card. I will google and see what I can find. Thank you for the help.

Hi, FitzLT. I've been experiencing the same issue on my ASUS G50 laptop. I tested the OSS and here is what I got:

Hi. I got the same problem after installing PC-BSD 8 on my ASUS g50 laptop. I tried to test OSS and here is what I got:

#osstest
Sound subsystem and version: OSS 4.2 (b 2002/201002091947) (0x00040100)
Platform: FreeBSD/amd64 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #10: Thu Jan  7 14:50:53 EST 2010     root@build8x64.pcbsd.org:/usr/obj/usr/pcbsd-build80/fbsd-source/8.0-src/sys/PCBSD


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).

The initial configuration at /boot/loader.conf is:

# Load sound-support
sound_load="YES"
snd_uaudio_load="YES"

Here is the log from /etc/rc.conf

# Enable sound-support
snddetect_enable="YES"
mixer_enable="YES"
oss_enable="YES"

The audio system works just fine under Windows 7 & Kubuntu 9.10
I have several items in sndstat:

#cat /dev/sndstat
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Realtek ALC663 PCM #0 Analog> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:4v/1r:4v channels duplex)
pcm1: <HDA Realtek ALC663 PCM #1 Digital> at cad 0 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:2v/0r:0v channels simplex)
pcm2: <HDA NVidia MCP78 HDMI PCM #0 Digital> at cad 2 nid 1 on hdac0 kld snd_hda [MPSAFE] (1p:3v/0r:0v channels simplex default)

I found the one who resolved the issue, here is the link

,but my laptop has another sound card than snd_es137x, it supposed to be snd_hda.
