Hello Alsa developers,
I would like to file a bug report about the Dell-WD15-Dock. This dock stopped working for me on archlinux/kde. The device was not picked up at all by pulse audio after some updates I installed last week. By trial and error I found out it was caused by the ucm profile that was added in alsa-lib 1.1.7. Running the following restored functionality.
sudo mv /usr/share/alsa/ucm/Dell-WD15-Dock/Dell-WD15-Dock.conf /usr/share/alsa/ucm/Dell-WD15-Dock/Dell-WD15-Dock.bak pulseaudio -k
I uploaded 3 alsa-info.sh profiles.
1.1.6 http://www.alsa-project.org/db/?f=a9a4c53d1e417c3d2ef304fe0778581c35b7a95e (working) 1.1.7 http://www.alsa-project.org/db/?f=bb474a687692e25f5e54c475f16f7ce4ef210f7a (not working) 1.1.7 http://www.alsa-project.org/db/?f=586dd059aaa08e839eb9df5f7b49990a5f4ad1a5 (working but moved the wd15 ucm profile)
https://alsa-project.org/main/index.php/Bug_Tracking pointed me to this mailing list to submit this report. If this is the wrong place or there is more information need could you let me know so I can send it to the proper channels?
Best regards,
René Santing
