snd_config_get_bool() was improved to parse also ASCII strings now,
|
||||
so we don't have to open-code the boolean parser in
|
||||
src/control/setup.c any longer.

From: Takashi Iwai <tiwai <at> suse.de>
|
||||
Subject: [PATCH RFC 2/2] Add workaround for conflicting IEC958 controls for HD-audio
|
||||
Newsgroups: gmane.linux.alsa.devel
|
||||
Date: 2012-10-12 15:25:49 GMT (16 weeks, 1 day, 5 hours and 49 minutes ago)
|
||||
|
||||
When both an SPDIF and an HDMI output are present on HD-audio, both
|
||||
try to access IEC958 controls with index=0 although one of them must
|
||||
be wrong. For avoiding this conflict, the recent kernel code moves
|
||||
the IEC958 controls of an SPDIF with device=1 once when the conflict
|
||||
happens.
|
||||
|
||||
In this patch, the corresponding support is added in alsa-lib side.
|
||||
The new "skip_rest" boolean flag is added to the hooked element
|
||||
definition which indicates that the rest of element array will be
|
||||
ignored once when this element is present and evaluated. With this
|
||||
new flag, the HD-audio config takes device=1 primarily, then take
|
||||
device=0 as fallback.
