I see that there is also a SNDRV_PCM_INFO_MMAP_VALID flag in the initialisations of the snd_pcm_hardware.info field. Should I comment that out too? May be a few days before I can test this out - I have just realised that a couple of my disk partitions are corrupted; I suspect one of the crashes of the audio driver is the explanation. I will have to restore from a backup first before continuing testing.
