Now I'm hopelessly lost and don't know what to try next.
You don't mention which version of oS you are using nor which audio source (onboard audio chip or a PCI/E audio card -- and which one did you make active in your BIOS?).
12.2 I ended up following links from the SDB recommendation and ended up at http://en.opensuse.org/SDB:Intel-HDA_sound_problems I ran $ head -n 1 /proc/asound/card0/codec* Codec: Realtek ALC888 HEY! That's just like on that page. In case you're concerned $ lspci -k reported 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2) Kernel driver in use: snd_hda_intel I've tried, as I said, http://en.opensuse.org/SDB:Audio_troubleshooting#A_possible_fix_to_choppy_.2... and http://en.opensuse.org/SDB:Audio_troubleshooting#STEP-1:_How_to_test_your_so... so i know the card works. As I said, I worked though the rest and got to http://en.opensuse.org/SDB:Audio_troubleshooting#STEP-5:_Add_.E2.80.9Cmodel.... and found that was my codex, so I did that change to modprobe.d as well. I passed over step6. The alsa docs explain how to determine of you should have users in the audio group or not. I call into the 'not' category. Which leads to http://en.opensuse.org/SDB:Pulseaudio OH WOW! Not even 11.4 tested! I get to step 8. As I said, http://phonon.kde.org/cms/1032 404s Step 9 is lacking. I only have the one card, but the KDE phonon back end has a different set of entries whenever I boot as I said above. The hardware level and surround-sound ones that appeared this after this AM' boot produce a sound when 'test'-ed but none of the also or pulse ones do. That's it for that SDB page except for $ aplay -vv /usr/share/sounds/alsa/Front_Left.wav ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused aplay: main:696: audio open error: Connection refused Yes, I'm repeating myself. Some of that's because I don't know what to do next.
Nevertheless, bear in mind that - seeing as you mentioned pulseaudio above - pulseaudio sits on top of alsa which means that you need to get your sound card first configured using alsamixer before pulseaudio will behave.
Every time I boot I see a different selection of devices available in the phonon "Device Preference". This morning, I see the surround-sound options that haven't been there before, and when I press 'test' they give sounds whereas none of the alsa or pulse items in the list do. However increasing their 'preference' doesn't help as the sound applications try connecting to pulse audio. As I say, I'm getting different vies of things every time I boot. Perhaps, as I alter settings, that's to be expected :-) But its confusing and doesn't help.
Also note that pulseaudio, at least in the past, did not allow alsamixer to display all the available channels of your card and I used to either uninstall pulseaudio or disable it (and I still do this - I have no need for pulseaudio) to be able to configure the channels. (Make sure you select the correct sound source in alsamixer - F6 I think is the key.) And if you decide to stay with pulseaudio then install pavucontrol to be able to configure pulseaudio.
$ alsamixer ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused cannot open mixer: Connection refused Through most of last year I had no problems with sound using pulseaudio. (Please don't tell me to stop using pulseaudio. That's just regressive and unhlpful.) Well OK, that was mostly with 11.4, but after and upgrade just before the new year it was still working. I'm wondering ... didn't we have a glibc upgrade ... ? I've also just tried setting up 12.2 on a scratch machine. There I have 00:05.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10) Kernel driver in use: snd_cmipci and that's just as lame. So I'm doing something wrong with both machines 'cos there's something I'm not groking. Yes, I'm using the output of CLI tools to report, but I'm also trying the various GUI tools, which are a little harder to report s text :-) I suppose I could upload snapshots but the usual result is, as I say, they can't connect, and when I run a 'ps' there's no pulse server listed. Yes I know. /lib/systemd/system/sound.target says StopWhenUnneeded=yes but I thought that pulse started when i logged in with KDE. (Please don't tell me to stop using KDE4. That's just regressive and unhlpful. And anyway, on the scratch machine I'm trying xfce4 and lxde and I get no sound there either.) Some of http://en.opensuse.org/SDB:Audio_troubleshooting is out of date for 12.x. Perhaps a clearer division between what applies to each revision is needed. -- "Realizing the importance of the case, my men are rounding up twice the number of usual suspects" - Cpt Renault to Major Strasser, Cassablanaca -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
