actually from what i know, pulseaudio does not go by ordering, but it prioritizes cards based on type like internal card vs usb card vs whatever... etc W dniu 19.08.2017 o 19:56, Janina Sajka via orca-list pisze:
Hi, John: I noted one comment in your post re pulseaudio that I want to respond to. John G Heim writes:... you can never guarantee that hardware devices are discovered in the same order. ...No, but you can control the card order they're assigned, e.g. via /etc/modprobe.d/alsa.conf using vid= and pid= params for multiple USB sound cards. The best on line summary of available approaches I've found to date is at: http://alsa.opensrc.org/MultipleCards I'm currently working through the above as I have a nagging problem every time I'm forced to reboot, e.g. after installing a new Linux kernel. My problem is that my hda device isn't always discovered. This morning I ran a system update and had to reboot some 30 times before my Intel-810 hda device was discovered. I've looked in the logs. The problem is the system is literally not seeing the device on most boots, yet once loaded, it runs perfectly for days and weeks. According to the above referenced article, there are approaches I might try to resolve my problem without rebooting. And, it seems my current ordering config code could be updated, too. Nevertheless, I offer my current code because it does work to reliably order my 5 sound devices. The always come up in the order defined below. My only issue is whether, or not card 0 has been found, else the remaining devices are shifted by 1--which doesn't help my situation as I need the headset to match my configured FreeSwitch config, just as one example. <begin config file code> alias snd-card-0 snd-hd-intel options snd-card-0 index=0 options snd-hda-intel id=PCH index=0 alias snd-card-1 headset options snd-card-1 index=1 options snd-usb-audio index=1 vid=0x1395 pid=0x3556 alias snd-card-2 cmedia options snd-card-2 index=2 options snd-usb-audio index=2 vid=0x0d8c pid=0x000c alias snd-card-3 ice options snd-card-3 index=3 options snd-ice1724 index=3 alias snd-card-4 hdsp options snd-card-4 index=4 options snd-hdsp index=4 <end config file code> _______________________________________________ orca-list mailing list orca-list gnome org https://mail.gnome.org/mailman/listinfo/orca-list Orca wiki: https://wiki.gnome.org/Projects/Orca Orca documentation: https://help.gnome.org/users/orca/stable/ GNOME Universal Access guide: https://help.gnome.org/users/gnome-help/stable/a11y.html Log bugs and feature requests at http://bugzilla.gnome.org
