It happens more likely with small buffers and sometimes doesn't happen with larger buffer.

Ok, what about the original issue? I don't quite get what we are doing here. It looks like we're debugging something completely unrelated, for example, I don't use the digital output like iec958 and this game doesn't capture sound so this is probably unrelated, too. I'm fine with improving ALSA but all this looks like other bugs and should probably be filed separately... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1315212 Title: [CA0106 - CA0106, playback] Playback problem - Surround dies, no valid output Status in ALSA driver: Confirmed Status in alsa-driver package in Ubuntu: Incomplete Bug description: This is tested against a Creative Labs Sounblaster live!

Both of them behave strangely, output coming through some, but not all speakers, etc. This was working in 13.10 under the sb0410. the ca0106 driver is the same for both cards.
