No Sound - Spdif TOslink Connected to A/V Receiver
I am still unsuccessful to get any sound from my speakers in Slackware 10.2 (default kernel 2.4). They are hooked up to my Pioneer receiver, which is then connected to my soundcard (Dynex DX-SC5.1) via optical spdif TOslink. I have found many people with the same problem as me, but many are left unsolved.
It works in windows using the "Envy 24 Family Audio (WDM)" driver (no cd driver required) and the only outputs needed are Master, Wave and PCM SPDIF. For listening to dvd movies, my receiver decodes the 44100 KHz signal. I tried a bunch of different slider combinations (including unmuting them) but still to no avail. Below is some more information about my system: Code:
bash-3.00# lspciCode:
bash-3.00# lsmod |
is there a driver for linux.
if this is that important to you, you can try linking it through wine. or upgrade your kernel. does knoppix or any other lin distro play nice with it? good luck. |

There is no driver on the cd and they don't support linux (I called them). I tried running mepis 3.3 live and still had no luck (recognized the same card, no sound).

Everything appears to be playing fine (ex. from xmms, aplay, xine), but there's still no sound.

ndiswrapper may be long shot since there is not a proper driver. i think one way this would work is you 'wrap' the windoz driver inside some lin code and give it a wirl.
or you can try using a generic one like sb. of course you could be done with it-- and buy a linux compatible card for your system and help support those that support linux :) again, good luck. |

default put .asoundrc in /etc/ |
I have Turtle Beach Catalina sound card based on the same chipset. Optical output works with snd-ice1724 module (kernel 2.6.14), however I had to put .asoundrc file to direct the sound to digital output. My .asoundrc (copied somwhere from internet):
Code:
pcm.!default {Also, I did not try watching dvd movies, so I don't know if pass thru dts works - receiver detects signal as pcm, not dts, and AFAIK computer sound cards produce only stereo pcm signal, not 5.1, except for the new dolby cards designed for x-box. Don't quote me on this - I'm not an expert. And I only interested in optical output, so I don't know if the .asoundrc disabled analog master output. |
This is awesome! It made my SPDIF work and I thank you.
Now.... I'd really like to get either passthru our 5.1 working via fibre. Everytime I run Xine and set it to 5.1 there is silence - assume it's spitting it out on the copper connectors. Passthru says the device is not available. Same exact .asoundrc as above. FC4 2.6.14-1.1656_FC4 on an Athlon. If I move the .asoundrc out of the way and use plug:spdif and 5.1 output with Xine I get sound but it's like the center channel is not right - not enough voice, mostly background music and the like. lspci output: [root@tv ~]# lspci 00:00.0 Host bridge: nVidia Corporation nForce2 AGP (different version?)

what do you mean mplayer balks?
and by passthough-- you mean you can listen while recordering (or doing anything else basically with sound)? |

(Quit) Am I correct in the understanding that HWAC3 will pass the Dolby 5.1 directly to my Denon receiver via TOSLink? My only objective with this machine is to watch DVD's in surround sound. I'm not doing anything else soundwise at the same time. I use Xine, but tried mplayer to see if I could make it work. Thanks. |
Update:
I ran speaker-test to plug:spdif as I'm certain that plug:surround51 is copper: # speaker-test -Dplug:spdif -c6 -t2 speaker-test 1.0.11rc2 Playback device is plug:spdif Stream parameters are 48000Hz, S16_LE, 6 channels Sine wave rate is 440.0000Hz Rate set to 48000Hz (requested 48000Hz) Buffer size range from 8 to 8192 Period size range from 4 to 4096 Periods = 4 Buffer time size 2525 To choose buffer_size = 8192 To choose period_size = 2048 was set period_size = 2048 was set buffer_size = 8192 0 - Front Left 4 - Center 1 - Front Right 3 - Rear Right 2 - Rear Left 5 - LFE Tone on each speaker except center and LFE. I'm perplexed but it proves what I thought I was hearing - no center channel..... Thoughts??? |
jake i asume you compiled mplayer
|
no, I installed it from an rpm just to test things. the more I fiddle with it - the more it seems like the .asoundrc needs tweaking
|
argg. i hate surround sound. turns out I'm only getting FL & FR via the optical out. grrr. what a pain and buttload of hours wasted on this darn thing....
|
I used kibiras' .asoundrc file and changed the device to my own (which I had overlooked before). This enabled me to get sound from 2 speakers with the speaker-test. I still had no sound in xmms though. After searching the net, I found that I needed to change the audio output plugin from OSS to alsa and I was amazed... I finally had sound.
Only problem remaining is getting sound from all other applications (ex. videos, flash, system sounds) to work. Any ideas? |
