I am having the following symptoms, before and after application of this
thread's patches:

- An onboard card
- A Logitech h390 USB headset
- alsa-info of: http://www.alsa-project.org/db/?f=942b5e96b53a667270f895ec5061ca14af0339ee

- 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?
