Description of problem: After starting up an IBM ThinkPad T23 and logging in to a GNOME session, sound is not working. However, /proc/asound etc. are present. Launching alsamixer shows the <Master> channel at 86%. Version-Release number of selected component (if applicable): pulseaudio-0.9.8-11.fc9 How reproducible: Always. Steps to Reproduce: 1. Boot IBM ThinkPad T23. 2. Log in to GNOME session. 3. Enable sound events. Actual results: No sound. Expected results: System sounds are working. Additional info: Executing system-config-soundcard and playing the test sound not only works but afterwards, the sound system as a whole also works until the system is rebooted. Issue assigned to PulseAudio; it might rather be an ALSA problem though.

Is this helpful to you? http://fedoraproject.org/wiki/LubomirKundrak/SoundTroubleshooting 1.) Does playback via ALSA work? aplay -D hw:0 /usr/share/sounds/startup3.wav 2.) Does playback via PulseAudio work? paplay /usr/share/sounds/startup3.wav 3.) What sound hardware do you have? hal-find-by-capability --capability alsa lsmod |grep snd
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I have absolutely the same problem with soudcard on my T23. Soundcard is detected (at gnome-sound-properties), but there is no sound until I run system-config-soundcard (from F8 package). After rebooting I have to do the same procedure to make it work again. 1) I tried if ALSA work, but with no success. 2) The same result like in first case was. 3) hal-find-by-capability --capability alsa: <pre> /org/freedesktop/Hal/devices/computer_alsa_timer /org/freedesktop/Hal/devices/computer_alsa_sequencer /org/freedesktop/Hal/devices/pci_8086_2485_sound_card_0_alsa_capture_1 /org/freedesktop/Hal/devices/pci_8086_2485_sound_card_0_alsa_playback_0 /org/freedesktop/Hal/devices/pci_8086_2485_sound_card_0_alsa_capture_0 /org/freedesktop/Hal/devices/pci_8086_2485_sound_card_0_alsa_control__1 </pre> lsmod |grep snd: <pre> snd_intel8x0 30492 1 snd_ac97_codec 94368 1 snd_intel8x0 ac97_bus 5504 1 snd_ac97_codec snd_seq_dummy 6660 0 snd_seq_oss 30364 0 snd_seq_midi_event 9600 1 snd_seq_oss snd_seq 48448 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 10124 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 42496 0 snd_mixer_oss 16768 1 snd_pcm_oss snd_pcm 67076 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 21640 2 snd_seq,snd_pcm snd 48312 12 snd_intel8x0,snd_ac97_codec,snd_seq_dummy,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 9288 1 snd snd_page_alloc 11400 2 snd_intel8x0,snd_pcm </pre> I also tried - modprobe snd_intel8x0 - but system-sonfig-soundcard seems to be only solution.
If you don't want to use PA for ALSA applications, remove the pulseaudio plugin from /etc/alsa/alsa.conf (Section "pre-load the configuration files").
I've removed that from alsa.conf, but the problem still persists.
Here is a workaround which might point to the root of the problem: 0. Log in to GNOME session - sound does not work. 1. Open gnome-volume-control. 2. Mute the PCM device by clicking the speaker symbol below the sliders. 3. Unmute the PCM device by clicking the speaker symbol again: sound works! Only now, 'aplay -D hw:0 /usr/share/sounds/startup3.wav' actually emits some hearable sound. Now, log out from GNOME session and log in again: sound still works. Reboot system and log in to GNOME session: sound does not work. Go back to step 1 to make sound work.
To be more precise: one also has to modify the volume level of the master channel either before or afterward to have the mute/unmute procedure take effect.
This seems to be an alsa pronlem then, reassigning.
I do have the same issue with non-working sound and my T23 in combination with XFCE in F9, but I have to perform the following steps: 1. Open volume control after login 2. Change volume of master channel 3. Change volume of PCM channel Then sound is working perfectly fine until rebooting. Issue remains with or without pulseaudio and configuration with system-config-soundcard works flawlessly.
Issue has been fixed in some kernel > 2.6.25.11-97.fc9.
