Ubuntu Multimedia :: Finally: Digital AC-3 Surround Sound With Pulseaudio ?

Oct 29, 2010

Here is the update to the old thread that somehow disappeared "HOWTO: A52 Encoded 5.1 Surround Sound Awesomeness with PulseAudio and ALSA on Hardy" thread (archived here). See also this bug report.There are two steps here: add the a52 plugin, and tell pulseaudio to use it.

Step 1:
Go to a terminal and do the following:

Code:
sudo bash
echo "pcm.a52 {[code]....

Pulse should come back on its own unless you disabled autospawn.Now pulse should be aware of your digital surround output. Go to System -> Preferences -> Sound. Click on the "Hardware" tab and change the profile to one of the 'Digital Surround 5.1' profiles. Play some sound (I like to test with www.pandora.com) and enjoy!If it doesn't show up, it probably means that alsa didn't create it correctly. To test if alsa sees the a52 device, type:

Code:
aplay -D a52:0

If it errors out (audio open error: No such file or directory) then that means it did not like your asound.conf settings. You might learn something by looking at the output of 'sudo alsa reload' or just 'aplay'.[code].....

Ubuntu :: Get Digital (5.1) Surround In 10.04 With Pulseaudio?

Jun 16, 2010

I would really like to get digital (5.1) surround in Ubuntu 10.04 with pulseaudio. However, when I go to the preferences->sound->hardware setting, I can only select analog surround outputs. The only digital outputs shown are stereo.

OpenSUSE Multimedia :: 11.4 - Lost Digital Surround Output

Mar 10, 2011

Alright so I just upgraded my 11.3 x64 to 11.4 using zypper dup and have now lost the ability to play digital output 5.1. Before doing the upgrade I was running alsa rather than phonon but apparently the upgrade decided to enable phonon, and I no longer show digital surround output. The soundcard I have is a CM8738 and I am using the coaxial output on it hooked into my receiver. In system settings->multimedia->phonon->speaker setup the soundcard shows and I have the ability to select different profiles.

However the digital output settings only show stereo and the sound output device the only one listed is CM8738 Digital Stereo (IEC958). I have selections for analog 5.1 and analog 7.1 but neither put anything out of the digital connection. As I said I was running alsa before and was able to do straight digital pass through which allowed my receiver to do the decoding and use all of my channels. How can I setup phonon to use digital passthrough, or switch back to alsa and get that setup again.

Ubuntu Multimedia :: Pulseaudio Digital Out Has Just Stopped Working

Oct 10, 2010

For no conceivable reason, pulseaudio will no longer output via the spdif connection on my onboard sound card.Up until now, various applications could output digitally (mostly using via the alsa plugin) fine. DVD playback would passthrough DD/dts bitstreams if the application was set to communicate with alsa directly. The sound profile in Ubuntu's audio applet would have to be set to Analog Stereo Output for this to work, no idea why.

Now, all the works is digital passthrough via alsa (i.e DVDs). So definitely not a hardware issue. Regular audio either via the alsa plugin or using pulse directly does not work so no music/system sounds/flash etc. All sliders are unmuted (see pics linked below) and the volume meters all show movement with sound activity. Changing the Profile setting does nothing, I thought maybe it had been fixed so digital actually meant digital.This has happened before (sometimes triggered by DVD playback and DD passthrough) but usually fiddling with the mute toggles fixed it.Possibly this has been caused by a recent update.

Ubuntu Multimedia :: Cannot Get Surround Sound In 10.04

Jul 16, 2010

Alsa says I'm using a HDA ATI SB audio card with realtek ALC662 rev 1. chip, I've set the default channels to 6 for 5.1 in /etc/pulse/daemon.conf but got only stereo.

; default-sample-format = s16le
; default-sample-rate = 44100
; default-sample-channels = 6
; default-channel-map = front-left,front-right

I would assume I have to do something with the channel map, but I don't know where to begin. I can say it is not a hardware issue as it works fine in windows 7 where my mic in is my sub-woofer/center out and my line in is my line in is my rear speaker out. I tried going into sound preferences to see if I could get it to use line in and mic in as sub-woof out and rear out , but there was no such option. All I was allowed was analog duplex 1 output / 1 input.

Ubuntu Multimedia :: 5.1 Surround Sound Bass Redirection?

Mar 5, 2010

When I decode an audio clip which contain 5.1 streams (the encoding doesn't matter - or does it?) I cannot find an option which allows redirection of the lower frequencies (from front, back and center channels) to the sub woofer (LFE channel). I understand that this perfectly normal and this is how 5.1 supposed to work. My problem is that my speakers are not full range, so they cannot reproduce the bass in the streams. What I want to know is if there is a way to do something like this: [URL]

Which is described as: Bass redir - Bass redirection. Route basses from all channels to subwoofer. Works only if it is subwoofer at output speakers. Highly recommended for systems with separate subwoofer. Basses are routed before mixing so basses are shown at LFE input level (although 'real' LFE may be absent).

I'm aware of the enable-lfe-remixing = yes option. It works fine for stereo, but not for 5.1

I use ubuntu 9.10 and my pulseaudio version is 0.9.19. The player I use most is SMPlayer (version 0.6.8 (SVN r3213)) and AC3-liba52 for AC3 decoding. My system is up to date.

Ubuntu Multimedia :: SPDIF Surround Sound Output?

Jun 4, 2010

Currently using an Asrock ION 330 with an SPDIF output and running 10.04It works as stereo but can't get the system to run as surround sound and everything shows as 2 channels only.The hardware itself supports it fine as it works under windows 7 without issues so it has to be a config issue somewhere.I have tried everything I can find via google including upgrading the alsa drivers but so far there has been no change.

Ubuntu Multimedia :: No Surround Sound On Realtek ALC892?

Oct 4, 2010

I've been trying to get my surround sound(5.1) to work for the past couple of of days, followed a number of guides, but nothing seems to get it working at all. I'm connecting the speakers using 3 analogue audio cables, I have tested and they work fine under Windows. When I go into the Sound options in Ubuntu I don't see a 5.1 profile listed under the Hardware tab, only stereo(and that works fine).

The sound controller is a Realtek ALC892 built-in to my mobo(Gigabyte P55A-UD3).

Here is some info I've seen requested in other threads, I'm running 10.10 RC, but I can assure you it doesn't work under earlier versions.

Code:
Linux Yurippe 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:32:27 UTC 2010 x86_64 GNU/Linux
Code:
**** List of PLAYBACK Hardware Devices ****

Ubuntu Multimedia :: Surround Sound Works As Stereo?

Nov 13, 2010

I just got a 5.1 Surround sound system and set it up. I found that it was only working as stereo, though (That is, only the two frontal speakers were producing any sound). I made sure everything was not muted in alsamixer and checked that the hardware was set to 5.1 in the Sound Preferences Hardware tab.

I'm using Ubuntu 10.10 64bit and my sound card is an onboard Intel DG41TY, Realtek ALC888VC codec.

Ubuntu Multimedia :: 10.10 - Enable Surround Sound Through HDMI

Mar 20, 2011

I have a Acer Aspire Revo R3600 running Ubuntu 10.10. Its a clean install, all I have done is update the NVidia drivers and ASLA. The PC connects to my AV Receiver via HDMI and I have stereo sound but no surround sound. If I go to System > Preferences > Sound and look under the hardware tab I only have "Internal Audio Digital Stereo (HDMI) Output" and no mention of surround sound or 5.1 etc. I assume this is part of the problem.

Ubuntu Multimedia :: 4.1 Surround Sound Doesn't Work

Apr 26, 2011

I have these Creative Inspire M4500 4.1 surround sound speakers.I got them to work succesfully on my older computer by installing the ALSAmixer. and then unmuting the channels. However on my new computer even after installing ALSAmixer, i cannot seem to be able to get playback from my rear two speakers. I tried the community ubuntu documentation and ALSA's own guide(which seemed too complicated for me.)

Ubuntu Multimedia :: 5.1 Surround Sound Plays Very Poor Quality

Nov 8, 2010

I got a 5.1 desktop sound sys for my recently built gaming rig. It sounds great. On Windows, that is. In ubuntu when I'm playing music, primarily when the subwoofer plays the bass, the speakers sound like they're farting and ripping phone books in half. Also, they get very statticy and sort of quiet. In sound preferences, analog stereo duplex is selected, if that's of any value. How can I get good sound playback in ubuntu?

Ubuntu Multimedia :: Surround Sound With ALC888 Intel DG31PR Gude?

Mar 16, 2010

Well i will write this down one more time i hope you don't delete it again To enable surround sound with ALC888 on Intel DG31PR for all versions of ubuntu inluding Lucid.(this works on other distros with alsa as well) gksu gedit /etc/modprobe.d/alsa-base.conf Find this line (if there is no such line (or the file is empty) it doesn't matter just add the next line and save it)(note that on older Ubuntu versions the file is named "alsa-base" as far as i remember): # Prevent abnormal drivers from grabbing index 0

Add this line after the #Prevent abnormal drivers from grabbing index0: options snd_hda_intel model=3stack-6ch-dig Then use this command to edit pukeaudio: gksu gedit /etc/pulse/daemon.conf

Find this line:
; default-sample-channels = 2
Change it to (make sure to remove the ; in front of it):
default-sample-channels = 6

I'm using a terratec EWX 24 96 sound card with ubuntu studio, and I have sound with the digital output, I have no sound with the digital input.

I had sound with the same configuration in Windows XP, and all the hardware is ok.

I think I have no sound at all, with Ardour or Rosegarden, that's like if the digital input was not here in jack.

Ubuntu Multimedia :: No Sound From Pulseaudio?

Jun 7, 2011

I seem to be having a problem with my sound. Every time I start my computer, I hear the sound played at the login screen and the sound played when I login. Right then, every time, the sound cracks up and stops before it finishes. Running "ubuntu-bug audio" shows that ALSA works fine but pulseaudio does not. For reference, "pacmd list" says that there are 0 sinks, 0 sources and 0 caches.

Edit: Solved by a really stupid mistake: loose 3.5mm audio cable. Don't do that. your sound and you're on a desktop computer, go, right now, and check to make sure that you haven't made the same mistake as me.

Ubuntu Multimedia :: Convert A Digital Sound Stream To Analogue Before It Is Sent To The Hdmi Out?

Jan 13, 2011

how to have alsa convert a digital sound stream to analogue before it is sent to the hdmi out? I would like to modify asound.conf. I do not have gnome as a desktop so I need to manually input the changes to asound.conf. The reason I ask is. I have sound going out of my acer revo to both spdif and hdmi. The spdif goes to my receiver and I want digital passthrough for that. The hdmi goes to my tv and I need it to be analouge before it gets to the tv. Right now, I get passthrough to both the spdif and hdmi. (the tv is all static) I want to have alsa convert the signal for the hdmi output only.

Ubuntu Multimedia :: Any Way To Have Sound Applet Without PulseAudio?

After some searching on the net I understood that it was part of pulseaudio, but now I feel a bit lost. Alsa works like a charm instead, but since I also want to use ubuntu to record sound I'm not sure if it will work, and also I have a sound source for my HDMI interface and don't know how switch if I want to.

Ubuntu Multimedia :: Mpd And Pulseaudio = No Sound When Playing In Mpd

Aug 14, 2011

Just like the title says, when I use mpd with pulseaudio, I get no sound but clients appear to be playing (ncmpcpp and gmpc). Other players such as vlc or mplayer work just fine. If I go under the mixer, I get "no application is currently playing or recording audio" under the "Applications" tab when playing through mpd. In contrast, when I'm using mplayer or vlc, both show up in that tab. It behaves as though pulse is simply not configured to work with mpd.Here is my config (edited out any commented line for brevity):

Code:

$ cat /etc/mpd.conf | sed '/#/d'
music_directory"/media/data/DM/Genre"
playlist_directory"/var/lib/mpd/playlists"
db_file"/var/lib/mpd/mpd.db"
