| Post subject: | HD Audio with Realtek 880 (Fixed) |
Hello, I got a SPDIF adapter for my motherboard a Gigabyte GA-K8N51PVMT-9, but I cannot get digital audio working for DVD, Live TV, music. Well Im not getting any sound at all. Here is what I get from aplay -l Code: card 0: NVidia [HDA NVidia], device 0: ALC880 Analog [ALC880 Analog]
Subdevices: 1/1 Subdevice #0: subdevice #0 audio output device: /dev/adsp passthrough output device: ALSA:iec958:{ AES0 0x02 } Enableed AC3 to SPDIF passthrough Enabled DTS to SPDIF passthrough Enable use internal volume conntrols Mixer Device: /dev/mixer Mixer Controls: Master Im running R5F27 recently patched. Tried everything here http://mysettopbox.tv/phpBB2/viewtopic. ... ight=audio but still didnt help. Im not sure where to go from here. Thank you. |

yapley Forget the SPDIF adapter for now. Have you ever had any sound out of your board or you just don't have sound out now? Is HD audio turned on in the bios? Run Code: lsmod | grep snd
and see if snd-hda-intel is in the list. TVBox |

Sorry for the long delay. Been busy with stuff like fixing up the house, work, oh and having a baby! Very fun stuff. Anyway yes audio has been working with the normal output from the motherboard, and here is the output from "lsmod | grep snd". Thanks. Code: snd_hda_intel 19096 0
snd_hda_codec 159232 1 snd_hda_intel snd_pcm_oss 42912 0 snd_mixer_oss 18176 1 snd_pcm_oss snd_pcm 69380 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss snd_timer 22404 1 snd_pcm snd 47588 6 snd_hda_intel,snd_hda_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 11360 1 snd snd_page_alloc 11784 2 snd_hda_intel,snd_pcm |

Well yaplej, life will never be the same again. The snd_hda_intel means your HD audio module is loaded which is good to hear. Open a X window and run /usr/bin/alsamixer and look for a column called IEC958 which is turned off by default. Use the M key to toggle the mute off. Quote: audio output device: /dev/adsp
passthrough output device: ALSA:iec958:{ AES0 0x02 } You may have to try audio output device: /dev/dsp IEC958 is the digital sound standard for (S/PDIF), you may have to Google on it. http://alsa.opensrc.org/DigitalOut http://www.knoppmythwiki.org/index.php?page=DigitalAudioHowTo Some of this stuff is old and don't apply.

I opened up alsamixer, but IEC958 is not one of the options there. |

When you had alsamixer open did you arrow over all the way to the right? Tab key will change to playback, capture and all. |

I did arrow over I also tried tab, and still didnt have that setting. Also here is the output from cat /proc/asound/pcm 00-01: ALC880 Analog : ALC880 Analog : capture 2 00-00: ALC880 Analog : ALC880 Analog : playback 1 : capture 2 Should there be a digital device there? Output from aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC880 Analog [ALC880 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 Again no digital device here either. I was playing around and installed alsa 1.0.15 from source using the wiki http://www.knoppmythwiki.org/index.php? ... AudioHowTo , but it didnt actually change anything so far. |

Is HD audio turned on in the bios? I have two separate machines both with SPDIF and both have a IEC958 column in alsamixer. Both machines are set with audio output device: /dev/dsp. I think dsp stands for digital and adsp is analog but I am not 100% sure of that. Both of my machines have the passthrough output device set to default |

Audio is set to "Auto" in the BIOS the only other option is "disabled". Currently Im using analog output by selecting /dev/dsp if I try /dev/adsp I get nothing. |

Could it be something in my /etc/modules.conf that isnt configured correctly? I have even tried the linux driver from Realtek, but still dont see any digital device. |

Just an update. I treid a knoppix live cd, and it failed to detect the digital audio device also. I then tried installing Windows XP Pro. After getting all the drivers installed the SPDIF output worked fine in Windows. So at least I know the hardware is working correctly just need to figure out how to make it work from Knoppmyth. Getting late gonna give it another try later today. Thanks. |

I found some info here. http://www.linuxquestions.org/questions ... -6-506308/ I tried the following command, and got the digital device to finally detect. Code: rmmod snd-hda-intel;modprobe snd-hda-intel model=6stack-digout
aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC880 Analog [ALC880 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC880 Digital [ALC880 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 After a rebooot the device disapears. How can I make this setting stick? Also the volume controls dont seem to work at all when using the IEC958 output either. |

Sorry for the repeated posts. Things have been moving along, and I want to keep the post updated. I was able to get my digital device to "stick" by doing the following. Code: to /etc/modprobe.d/aliases add this line
alias snd-card-0 snd-hda-intel to /etc/modprobe.d/alsa-base add this line options snd-hda-intel enable=1 index=0 model=6stack-digout Found this here. http://www.linuxquestions.org/questions ... ba-585577/ http://www.linuxquestions.org/questions ... -6-506308/ http://ubuntuforums.org/archive/index.php/t-219631.html Im still having the issue with spdif not working until you run something through the device with it muted, and then unmute. Its described here, but the /etc/rc.local trick does not seem to work in my case. http://www.mythtv.org/wiki/index.php/In ... tek_ALC88x |

I got the spdif issue fixed on boot. Turns out the rc.local is not how scripts are ran for Knoppmyth. Here is how I got it working. Code: to/etc/init.d/spdif add these lines
amixer set IEC958 mute aplay -Dplug:iec958 /usr/share/sounds/alsa/test.wav amixer set IEC958 unmute make the script executable chmod +x spdif to install the spdif script update-rc.d spdif defaults to remove the spdif script rm /etc/init.d/spdif update-rc.d spdif remove http://www.mythtv.org/wiki/index.php/In ... tek_ALC88x http://www.youtube.com/watch?v=d39izaupvEg |
