[v3,0/6] ALSA: emu10k1: add support for high-bitrate modes of E-MU cards

Message

Oswald Buddenhagen July 17, 2023, 10:20 a.m. UTC

This series is what all the work was about: support the "dual-/quad-pumped"
modes of the E-MU cards.

i'm posting this so the final version (unless some actual bugs are found) is on
record, without expectation of it being applied. i'll document its availability
on the wiki and the related bug report instead.

the first three patches appear uncontroversial, and you may apply them if you
want to. however, the added value is somewhat limited without the last three
patches, so it's probably not worth bloating the driver with them.

v3:
- rebased onto pulled ahead series
---
This patch series needs to be applied on top of the patch titled "ALSA:
add snd_ctl_add_locked()".
