Re: [alsa-devel] valgrind error in snd_tlv_get_dB_range

Yes, these are errors in valgrind.

As I understand the problem is that init_db_range initialize invalid rec->db_info, because snd_hctl_elem_tlv_read failed to fully initialize tlv:

snd_hctl_elem_tlv_read initializes as many bytes as needed.

I'd guess valgrind doesn't notice this because this is done through an ioctl, in the kernel.
