I have an intel hd audio based systemboard, in fedora 17 I followed http://www.johannes-bauer.com/linux/dolby/ to get 5.1 surround working on the optical out. It worked great until I removed nvidia drivers due to some problems in X and would no longer start x. I installed fedora 19 and followed the notes I had taken when I originally got it working. I am not able to get the optical to list as 5.1 again in fedora 19 Any suggestions would be appriciated. in pulse audio volume control if you select 5.1 analog there is no option to select port digital output. it lists that as a seperate device. digital out is listed as a 2 channel device. When it was working in 17 I have 5.1 and 2 channel versions. in my notes I had to add packages a52dec @ rpmfusion-free a52dec-dev @rpmfusion-free alsa-plugins-freeworld-a52 @ rpmfusion-free ffmpeg @ atrpms libavcodec52/53/54 libavdevice52/53/54 libpostproc52 I edited my alsaconfig and added most of what was listed in that article which got the upconversion on all audio that wasn't already 5.1. My amp listed it as 5.1 audio all the time and it sounded a bit richer as well as some improved positional on 2ch sound. My only downside was a few apps like twinkle voip client couldent figure out how to use the mike? or would want exclusive access to the sound system. I would also like to find a way to fix that so that all apps could happily share even if it is creating a virtual sound device for those apps to use and it gets mixed in with all the rest of the sound. My current device list which does have the added parts from the alsa config for upmixing and pavucontrol does list the sections I added but is not using them. I have also edited the dameon.conf to set default sample rate lfe upmix and default channels to 6 with no change. pulse PulseAudio Sound Server upmix51 Upmixer channel expander sysdefault:CARD=PCH HDA Intel PCH, ALC892 Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog Front speakers surround40:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=PCH,DEV=0 HDA Intel PCH, ALC892 Digital IEC958 (S/PDIF) Digital Audio Output -------------- next part -------------- An HTML attachment was scrubbed...
