Comment(by dsd):

 One option, at least for the short term, is to restrict the offered rates
 to those that have "OK" in both columns above. They are:

                 .rate_min       = 8000,
                 .rate_max       = 48000,
                 .rates          = SNDRV_PCM_RATE_8000 |
                                   SNDRV_PCM_RATE_16000 |

 In this configuration, I can run the above testing matrix with only one
 bad sound produced: 22050Hz (which is downsampled to 16000 by alsa) with 1
 channel has some blips (2 channels is fine).
