I am having the following symptoms, before and after application of this thread's patches:
Given: - An onboard card - A Logitech h390 USB headset - alsa-info of: http://www.alsa-project.org/db/?f=942b5e96b53a667270f895ec5061ca14af0339ee
When: - I do: aplay $(locate .wav | grep Front) it outputs: alsa ALSA lib pcm_direct.c:980:(snd1_pcm_direct_initialize_slave) unable to install hw params ALSA lib pcm_dmix.c:1030:(snd_pcm_dmix_open) unable to initialize slave aplay: main:682: audio open error: Broken pipe - I do a Skype "Make a test sound" /var/log/messages streams dozens of these: kernel: cannot submit urb 0, error -28: not enough bandwidth
Note that this is a new laptop and headset, so I haven't compared how either works on other setups, such as with other kernels or alsa versions.
Any hints? Any further info needed?
Thanks! —☈
