[alsa-devel] AudioFire4 quirk http://mailman.alsa-project.org/pipermail/alsa-devel/2015-July/095697.html
Linux 3.16 or later have this issue.
As long as I investigate, this issue depends on firmware version installed in these devices. While, it's not clear that which version of firmwares for which model has this quirk. At least, firmware version 5.7.0, 5.7.3 and 5.8.0 for AudioFire2/AudioFire4/AudioFirePre8 have this quirk.
This patchset applies a solution for this issue, with my assumption that 'the same firmware binary has the same quirk'. These models, AudioFire8 (since Jul 2009) and Gibson Robot Interface Pack (RIP) series uses the same firmware binary in driver package.
If possible, the second patch should be applied to all of stable kernels.
This patchset updates my previous RFC: [alsa-devel] [RFC][PATCH 0/2] ALSA: fireworks/firewire-lib: add support for recent firmware quirk http://mailman.alsa-project.org/pipermail/alsa-devel/2015-August/095849.html

Thanks for applying them. (And sorry to be late for reply because I got a short summer vacation.)
Currently I'm preparing for the next patchset (Digi00x and TASCAM drivers). As a quick glance, for-next branch in sound.git doesn't still includes these two patches. In this case, which branch should my work reabases to?
Use for-linus branch for now.
