#11334: XO-1.75 audio sounds terrible in some configurations

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_11025 |
SNDRV_PCM_RATE_16000 |
SNDRV_PCM_RATE_32000 |
SNDRV_PCM_RATE_48000,
}}}
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).
