In the log files, there was written: "Failed to load module "module- alsa-card"".
http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa /module-alsa-card.c So the module-alsa-card takes the arguments card_name and card_properties and I used module-alsa-sink and module-alsa-source where this is different and that confused me a bit. There must be another reason why the module-alsa-card fails: >>> load-module module-alsa-card device_id="0" >>> name="usb-EDIROL_UA-101_ZT82634-00-UA101" >>> card_name="alsa_card.usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false >>> tsched=yes ignore_dB=no deferred_volume=yes >>> card_properties="module-udev-detect.discovered=1" Module load failed. >>> load-module module-alsa-card device_id="0" >>> name="usb-EDIROL_UA-101_ZT82634-00-UA101" namereg_fail=false tsched=yes >>> ignore_dB=no deferred_volume=yes Module load failed. >>> load-module module-alsa-card device_id="0" Module load failed. >>> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986817 Title: UA-101 - UA-101, playback Pulseaudio fails to detect card To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/986817/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
