Likely a side effect of these two:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7546abfb8e1f9933b549f05898377e9444ee4cb2

If so, it means Pulseaudio still does something inoptimal (i.e. what if
the card actually had only a single playback stream? it would still be
broken).
