alsa-info output for the last working kernel
I'm having the same problem with snd_hda_intel. I always thought the sound was too quiet to being with (much louder in Windows) and now it basically just a whisper. Interestingly my headphones seem to work about the same as normal, only the speaker output is suppressed on this system. This is a Dell D830 laptop. Let me know if alsa-info is of any real value and I can post it. OK, I feel silly. I was able to correct the speaker output level by using "alsamixer -c 0" and increasing the "Speaker" control to 100. I could find nowhere in the GUI to control this particular setting, either in the Sound Preferences applet or the Pulse Audio Control application, but setting it from the command line is trivial. I'm not sure why this works with the old kernel without doing this but at least I have audible sound now. > OK, I feel silly. Ahem! Why? In my case "Speaker" control is totally ineffective but playing with various controls I found that in my case bumping up 'VIA DXS Playback Volume' makes a difference between a "whisper" sound and what looks like normal. This is the whole difference in an output of a 'store' command for alsactl: @@ -443,8 +443,8 @@ comment.dbmax 0 iface MIXER name 'VIA DXS Playback Volume' - value.0 0 - value.1 0 + value.0 29 + value.1 29 } control.47 { What is more with 2.6.29.6-217.2.16.fc11 and earlier kernels these settings were by default at maximum and went down to 0 for 2.6.30.5-43.fc11 killing sound. amixer shows now zeros also on the remaining three 'VIA DXS' channels, whatever that may be, but those settings do not seem to matter in my particular setup. > I could find nowhere in the GUI to control this particular setting, You should be able to do that via gst-mixer (a.k.a. "Advanced Volume Control" on "Preferences" menu) but you have to turn that on using "Preferences" button of that application; most of controls by default are not displayed. With pulseaudio tools you are SOL. Probably unrelated but anything associated with sound generates reams of shm_open() failed: Permission denied shm_open() failed: Permission denied shm_open() failed: Permission denied shm_open() failed: Permission denied errors. Not that surprising as /dev/shm/ is "drwxr-xr-x 2 root root" but Fedora 11 was always doing that. It appears that problems with a sound killed by "VIA DXS" settings are pretty old. Searching through Google brings, for example, that one http://forums.gentoo.org/viewtopic.php?t=230823 from 2004. What this "DXS" stands for nobody seems to know. :-) What changed for snd_hda_intel (see comment #2 and comment #3) I cannot tell. This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
