It looks like a rate plugin issue. Post > also snd_pcm_dump() output. Driver does not do any alignment. It's front:0. I don't think the rate plugin is used. Device is being opened with SND_PCM_NO_AUTO_RESAMPLE|SND_PCM_NO_AUTO_CHANNELS|SND_PCM_NO_AUTO_FORMAT and snd_pcm_hw_params_set_rate_resample(..., 0). That should get me only softvol, right?
