As add'l info with guidance from #irc, I've tried adding /etc/modprodbe.d/50-sound.conf ... + options snd-hda-intel power_save_controller=0 and adding /etc/init.d/after.local ... + hda-verb /dev/snd/hwC0D0 0x1c SET_POWER_STATE 0 and launching cat /usr/local/scripts/alsa-fix.sh #!/bin/bash sudo hda-verb /dev/snd/hwC0D0 0x1c SET_POWER_STATE 0 as a KDE startup script, and exec'ing hda-verb /dev/snd/hwC0D0 0x1c SET_POWER_STATE 0 @ desktop shell as uid=<myuser> None work. The one thing that DOES work, so far, is @ desktop shell, exec of sudo hda-verb /dev/snd/hwC0D0 0x1c SET_POWER_STATE 0 as sudo (root). On exec, I hear a 'pop' through the speakers, and immediately after I can play audio -- withOUT having to physically UNPLUG/REPLUGIN the jack. Clearly, I can't figure out how to automate this workaround -- not clear where else to try it. Begs the question why it only works in this case. - Rob

It's a known problem with VIA codecs, and the fix was already merged in 4.2-rc1, the commit 735c75cf4d434862e38c01dcfb2ce8d2fcb9035f. The next stable 4.1.x kernel should contain the fix. thanks, Takashi

I didn't realize the script wouldn't grab the important info needed. I think this does say it's a VIA codec here? aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: SB [HDA ATI SB], device 3: VT1708S Digital [VT1708S Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 cat /proc/asound/card0/codec* | grep Codec Codec: VIA VT1708S

The script includes the information, but your mail didn't, so I had to start a browser, and read it through by myself. If the codec chip was mentioned in the mail, I could answer in a second. So, please, at the next time, give your hardware detail concisely in the mail itself. This will save lots of time. thanks, Takashi

I'd have put the script output INTO the email if the list didn't limit the size of the mail and refuse to accept it. It would save time if that limit didn't prevent including the info we're asked to provide.

It would save time if that limit didn't prevent including the info we're asked to provide. Well, sorry, you miss the point. Although alsa-info.sh contains the whole things, it's too lengthy. The problem is not about whether you attach it or copy the URL. It's about the attitude to ask something. Imagine you are asking someone the place of your favorite restaurant. Would you give just a thick address book that includes your marking? No, usually you tell the name or the address of the restaurant. Then some people might already know and can explain even without reading through the whole book. If not told, people won't pay attention to your question (who dare read the whole book?). In general, it's important to know which information to give for asking something. For a sound problem, usually the hardware information (the machine model, the codec chip, etc) is the starting point. Attaching alsa-info.sh outputs helps indeed, and often requested; but this is rather a subsidiary thing. Just a more couple of lines to describe your hardware often helps people to understand the problem itself better. Takashi
