|
|
Hello,
I have the following problem:
Kde Notifications:
Code: | The audio playback device HDA Intel PCH (ALC3202 Analog) does not work.
Falling back to . |
... I have sound in e.g. firefox -> YouTube Video but in programs like vlc
What that mean?
Code: | # lspci
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
|
Code: | # dmesg | grep -i audio
[ 1.501949] thinkpad_acpi: Console audio control enabled, mode: monitor (read only)
[ 2.050559] #29: ThinkPad Console Audio Control at EC reg 0x30, fw unknown

On my Thinkpad X301:
Code: | # dmesg | grep hda_codec
hda_codec: CX20561 (Hermosa): BIOS auto-probing. |
Code: | # ls /dev/snd/
by-path controlC0 controlC29 pcmC0D0c pcmC0D0p seq timer |
These commands show that the sound device is being detected by the kernel and that it is loading the right driver. How about on your system?
If these look comparable, then maybe you need to set up ALSA mixing, as described on the wiki. _________________ Personal overlay | Simple backup scheme |

Hello,
Code: | # dmesg | grep hda_codec |
... with no result. Is that good or bad?
Code: | # ls /dev/snd
by-path controlC29 hwC0D3 pcmC0D0p pcmC0D7p seq
controlC0 hwC0D0 pcmC0D0c pcmC0D3p pcmC0D8p timer |
... looks good I think?
I dont know what the problem is? |

emerge alsa-utils, then run "aplay -L"; my output:
Code: | # aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

If you see a comparable array of devices, that's good.
Then, you can test the sound playback directly with the "speaker-test" command, or running aplay on the WAV files /usr/share/sounds/alsa .
If these work, then the problem is with the mixing setup or KDE. _________________ Personal overlay | Simple backup scheme |

Check to see if you have the alsa flag in vlc
as I suspect you don't and that's why vlc doesn't have sound.
On the no sound in KDE, I don't see any flags that could be causing the problem so it's likely a configuration issue as Hypnos suggests.
I doubt that it's a kernel config issue as you have working sound in Firefox |

Where do you see the message? dmesg, KDE pop-up, somewhere else?
If it's a KDE pop-up, try following the instructions on that page I linked. _________________ Personal overlay | Simple backup scheme |

For some reason you seem to have the reverse problem -- default is not working. So you can try placing HDA Intel PCH above all the others and see if that helps.
Do you have an ~/.asoundrc that manipulates default in some way? If so, maybe first try getting rid of that. _________________ Personal overlay | Simple backup scheme |
