eMachine er1401 HDMI audio not working

A

andyzammy

I'm unable to get the eMachine to output sound through the HDMI cable. It works fine out of the 3.5mm jack.
Code: 
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Realtek ALC662 PCM #0 Analog> (play/rec) default
pcm1: <HDA Realtek ALC662 PCM #1 Digital> (play)
pcm2: <HDA NVidia MCP78 HDMI PCM #0 Digital> (play)

After I type
# sysctl hw.snd.default_unit=2
switches pcm2 to default but still no sound.

Looking at pciconf I think that a driver might not be recognised:
Code: 
hdac0@pci0:0:7:0:       class=0x040300 card=0x04481025 chip=0x077410de rev=0xa1 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    class      = multimedia
    subclass   = HDA

snd_driver_load is set in rc.conf. AFAIK this loads all available audio drivers. Does this mean that FreeBSD doesn't currently support HDMI sound for this graphics card (GeForce 9200)? x11/nvidia-driver is installed, I'm not sure if that is what supports the HDMI audio though.

I have seen similar threads on here sending the users to nvidia support so I will do the same if there haven't been any revelations since the other threads. Is there anything I haven't checked yet?
 
The hardware is recognized. If it wasn't it wouldn't show up in /dev/sndstat.

Instead of loading everything, only load snd_hda(4). You may need to fiddle with the outputs.

When you say outputs do you mean the gpio? The only thing I can think of doing would be to set hint.hdac.gpio0-7.config all to 'Digital-out' in device hints.
 
Okay, ignore last post. I need to see current configuration but i can't seem to capture the pindump.

# sysctl dev.hdac.0.pindump=1 >& file

Results in a file with only one line:

Code: 
Dev.hdac.0.pin dump: 0 -> 0

I take it I am not capturing stderr properly?
 
I'm still not sure how to capture the pindump. It looks to be a kernel message that is printed to tty0 but I thought they still came out of stdout or stderr Not sure where the log file is that syslog makes. The part of the pindump I could see told me that nid7 nid9 nid11 and nid13 are Digital-out pins, which I took to be the HDMI audio. They were marked [DISABLED], so I added the following device hints:
Code: 
hint.hdac.0.cad3.nid7.config="conn=Jack"
hint.hdac.0.cad3.nid9.config="conn=Jack"
hint.hdac.0.cad3.nid11.config="conn=Jack"
hint.hdac.0.cad3.nid13.config="conn=Jack"

This didn't work, but changed the dmesg from this:
# dmesg | grep hdac

According to the device description under boot-time configuration, assigning a connection type other than "None" should leave the pins in an "enabled" state. I'm not sure what I'm doing wrong. Am I on the right track?

I think you're experiencing the same problem as myself and many other nvidia users. HDMI audio just doesn't seem to work unfortunately.

I tried the nvidia forums and got this rather sad reply:

Is there a reason you cannot use a more stable BSD distro like PC BSD or Debian BSD or a true Unix like Solaris? You are using an unsupported niche FOSS OS, and without the massive community of Debian or the financial backers behind PCBSD --FreeBSD is highly unstable IMO. I personally view Free BSD as an OS only fit for entirely FOSS drivers (which Nvidia no longer provides) b/c you will likely need to modify the subsystem for your specific hardware and software needs.

I wouldn't even classify FreeBSD as free b/c you have to buy so much beer to get a working system that you could have bought a copy of Windows. --I jest, but in all seriousness you are going to be in for headaches with FreeBSD and Nvidia drivers.

I can verify that HDMI audio works in Debian BSD, PCBSD and Solaris, and I can attempt to reproduce your issues, but you will likely get better support by posting in the Free BSD forums.http://forums.freebsd.org/ If you are new to this be prepared for headaches]http://www.debian.or...s/kfreebsd-gnu/[/url]

Hi taliz, thanks for your reply! I'm not really sure what to make of this guys post. It's a very mixed signal, he knocks the OS, offers some assistance then suggests rebuild from base? I guess the rebuild is being suggested in case the issue is fixed in CURRENT/STABLE branches?
 
The funny side in the quotation above is that PCBSD mentioned there uses unmodified FreeBSD kernel and only difference is in configuration. So everything that works on PCBSD should also work on vanilla FreeBSD. As soon as there are both positive and negative feedback about NVIDIA HDMI, I suppose that problem cause is somewhere in cards or in connected HDMI devices.

Well, the problem is not with the cards/devices as it works fine in Linux. Also the issue might not be with the kernel, but with how the sound system works(but I'm just guessing here).
 
Wondering if anyone has gotten any further with this? Also if this problem is with both i386, amd64 on 8.2 and 9.0? I am having the same issue with an ION board with 8.2 amd64.
 
Just a small bump, I installed Windows for xmas just to be able to view something and am now interested in fixing this again (if it's possible).

I recently noticed that the eMachine which I'm having trouble with has the same NVidia audio device as my laptop (MCP78), and this has definitely worked in the past (on FreeBSD). I know that this spurious problem crosses operating systems (ie, works in Windows/Linux, but for whatever reason not on FreeBSD), but does the fact that if it works on my laptop mean that it should also work on the eMachine?

MCP78 is a HDA controller, while the main question is to HDA CODEC. And HDMI CODEC is much bigger question.

I don't wish to promise anything, as I am not sure that my receiver supports HDMI audio at all, but I'll get some NVidia card and try to experiment with it.
