[opensuse] analog sound fallback output gone after switch to digital output
I've lost the ability to switch back to Analog Stereo Duplex sound output, or rather, whilst the option remains, doing so results in no sound. But it was working fine before I switched to digital and even for a short while after I made the change I could fall back on it when required. I'll explain the setup and why I need to do this. openSUSE 13.1 64-bit with Evergreen updates, KDE 4.11.5, PulseAudio I have a Dell Latitude D630 laptop. There is an integrated speaker and headphone out/mic in jacks. Under KInfoCentre the internal soundcard shows as 'HDA Intel (STAC9205 Analog)'. The laptop spends most of its time on its docking station, a Dell PD01X. Until recently I had the sound set to 'Analog Stereo Duplex' in PulseAudio Volume Control's configuration. All worked fine. I would plug a small pair of speakers into the laptop's headphone jack when docked, or listen through the crappy internal speaker when undocked. The jack autodetects if something is plugged in and adjusts accordingly. I recently invested in a new hi-fi amp with various inputs including coaxial, so decided to hook it up to the coaxial out on my docking station. I switched to 'Digital Stereo (IEC958) Output + Analog Stereo Input' in PAVU's configuration. In KInfoCentre I see 'HDA Intel (STAC9205 Digital)'. Digital sound outputs fine to the hi-fi. I then found that the laptop headphone jack no longer worked, but there is a second headphone jack on the docking station that had never previously worked. That seems to work only in conjunction with digital out, so plugging into that jack instead works fine now for the little speakers. Indeed, it's more logical since I don't have to plug and unplug speakers every time I dock the laptop. When I take the laptop away I still require sound from the internal speaker, but it seems I can't have both digital and analog output concurrently. So I would switch back to 'Analog Stereo Duplex' in PulseAudio Volume Control. For a short while, this worked fine. Now it doesn't. I cannot get sound from either the internal speaker or the headphone jack on the laptop. I've been through the settings in every place I can think of. Everything seems correct and unchanged in Alsamixer. I've tried changing the device order and resetting to defaults in KDE Phonon settings. I've also gone into YaST sound, deleted the sound device, rebooted, reconfigured the sound device. Unable to find any editable PulseAudio configuration files, I tried simply deleting all PulseAudio files that I could find and restarting. No joy. Since I have another user account I tried logging in there. That had never been changed from Analog Stereo Duplex but I can't get sound there either any more, so something has changed at system rather than user level.

Isn't it always the way that you battle with something for days or weeks, then the moment you post on here you stumble across a solution? The act of posting here must confer some kind of onus or guilt on the part of the poster to double-check / octuple-check everything. Alas I can't adequately explain what I've done to make it work. I thought I'd switch over to Analog Stereo Duplex, then open PAVU, KDE Phonon Settings and Alsamixer all together and observe what happens when I unplug the small speakers from the docking station. Answer: nothing. That jack doesn't appear to have any sensor so there is no speaker toggle. I went along the levels in Alsamixer and deselected 'Beep', toggled 'Auto-Mute' to Enabled, then tried the speaker test in Phonon again. Miracles occurred. Sound from the internal speaker. So I went and toggled the Beep and Auto-Mute settings again to see which was responsible. Neither. Speaker continues to work now. Total nonsense. At least temporarily I've resolved the problem without understanding anything at all. :-/ gumb -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
