Listmates,
I have the most atavistic sound known to mankind on my laptop running arch. Sometimes it works, sometimes it doesn't. The card specs are:
0:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) Subsystem: Toshiba America Info Systems Device ff08 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64, Cache Line Size: 32 bytes Interrupt: pin ? routed to IRQ 16 Region 0: Memory at f8700000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel
The Intel modules loaded are:
snd 65928 13 snd_seq_oss,snd_seq,snd_seq_device,snd_hda_codec_realtek,snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer snd_hda_codec 68112 2 snd_hda_codec_realtek,snd_hda_intel snd_hda_intel 29256 1 snd_page_alloc 9760 2 snd_hda_intel,snd_pcm snd_pcm 80920 3 snd_pcm_oss,snd_hda_intel,snd_hda_codec
When I first start arch and start kde, everything is fine. However, if I log out and then back it, most times the sound is gone -- dead. The sound will not start again until I reboot. Anybody got any ideas on what to check or what to keep a watch out for? Also, any ideas on how to bring the sound back once it dies without having to reboot?
Thanks for any help you can provide. I always hated chasing sound problems.
snd-hda-intel encompasses many different chipsets/codecs. Which one does your card use? You can find out like so: [darose@daroselin ~]$ grep Codec /proc/asound/card0/codec#0 Codec: IDT 92HD71B7X As far as general things to check/try: * Try restarting the KDE sound system. * Try checking to see if anything got muted in the mixer (i.e., check in Kmix or alsamixer). * Try seeing if this is a KDE issue or not by hitting ctrl-alt-F1, logging into a non-X console, and testing the sound using alsaplayer. * I had a problem with my sound card whereby "analog loopback" was getting set and muting the sound. (See: http://bbs.archlinux.org/viewtopic.php?pid=535521#p535521) Tore my hair out over that one for a LONG time. Maybe this is your issue too? HTH, DR
