Hello All, I'm using Debian Testing with KDE desktop, and having problem with PulseAudio's sound card detection. The system I'm using has three sound sinks (or cards if you wish): - nVidia GTX680's sound output over DisplayPort. - Intel's on board HD audio. - ASUS Xonar D2X on PCIe (CMedia CM8788) [Preferred & default card]. All of the cards are well supported under Linux, ALSA and PulseAudio, however PulseAudio is sometimes do not detecting my soundcard and revert to one of the other cards as it pleases. The problem started with a kernel update (I don't remember the exact version). What I've diagnosed is as follows: - Card is always operational. Present in lspci, initialized correctly (D2X has hard relays as mute switches and I hear the distinctive CLACK sound when the card is initialized). - ALSA always detecting and calling the card settings from persistence as it should, I verified with ALSA mixer. - Deleting PulseAudio settings and restarting daemon generally has no help. - When card is not detected it's completely absent from PulseAudio's configuration and configuration database. - I sometimes need to shutdown and restart the PC two to three times to get the sound card back. - It's more likely occur if I log-on to my PC late (press the power button, get a cup of tea, drink some, wander off and login). - There's no terse/warning/error logs anywhere. Everything is working as it should on paper, so I cannot debug the problem. Did anyone experience anything like this? I have the ability to debug and patch the code if necessary, and if someone can at least show me the right place for discussing this stuff I'd be grateful.
I'm having the same problem on Kubuntu 18.10, PulseAudio 12.2. `pactl list cards` does not list D2X but it is clearly present in `aplay -L` and `alsa-info` output.
Were you able to resolve or debug the problem? _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
