fit in the number of bits used for the port still does something.
This fixes PR pkg/18741 for ac97-based hardware. Other audio drivers
might need a similar fix.
controls. As it was before, the master volume control in all mixer programs
did nothing. It seems that this codec is not correctly wired in (almost?)
all motherboards.
Patch by Quentin Garnier. Fixes first part of PR kern/22548.
Add codec id of VT1616.
ALC650 codec specific chagne:
Add outputs.surround.mixtofront,
outputs.center.mixtofront, and outputs.lfe.mixtofront.
VT1616 codec specific change:
Add outputs.surround.mixtofront,
outputs.center.mixtofront, and outputs.lfe.mixtofront.
(Not tested)
XXX: We should provide ac97(4) manual page and describe
codec-specific features.
- Add "outputs.surround", "outputs.center", and "outputs.lfe"
- If the codec is not capable of a feature, mixer variables
about the feature is not created. For example, no
"outputs.tone" for a codec without tone control.
- Set the following mixer values in ac97_attach():
outputs.master=127,127
outputs.master.mute=off
outputs.headphones.mute=off
outputs.surround=127,127
outputs.surround.mute=off
outputs.center=127
outputs.center.mute=off
outputs.lfe=127
outputs.lfe.mute=off
inputs.dac.mute=off
inputs.cd.mute=off
inputs.line.mute=off
inputs.aux.mute=off
inputs.video.mute=off
record.volume.mute=off
because the default setting of AC'97 codec (all mutes are on,
and maximum volume) is troublesome.
- Make "char*" parameters of ac97_get_portnum_by_name() "const char*"
Codec ID changes:
- If a codec ID is unknown but its vendor ID is known,
ac97_attach() prints the vendor name like "dev0: <vendor name>
unknown (0xXXXXXXXX) codec;"
- Add IDs of Asahi Kasei AK4542, AK4544, AK4544A, AK4545,
Realtek ALC100
- Correct a vendor name: "Advance Logic" -> "Avance Logic"
- Add capability of codec-specific initialization
ac97_attach():
- CDAC, SDAC, and LDAC are eanabled.
- DELAY() before mixer settings. ThinkPad X24 needs it.
ALC650 codec specific change:
- Add "outputs.surround.lineinjack" to switch the line-in jack
to the surround output
- Add "outputs.center.micjack" and "outputs.lfe.micjack" (alias
of "outputs.center.micjack") to switch the mic jack to the
center/lfe output.
ac97_attach(): Enable VRA/VRM if the codec is capable of them.
The struct ac97_softc keeps the clock of the codec, the basic
features flag (the value of AC97_REG_RESET), and the extended
features flag (the value of AC97_REG_EXT_AUDIO_ID).
ac97_codec_if: Add get_extcaps(), set_rate(), and set_clock()
methods.
* support devices that crash when reading the codec registers; a flags
interface is added to the host interface and one flag is defined
(AC97_HOST_DONT_READ).
* new API (restore_ports) for restoring the user's settings. This
can be useful after an APM resume after a suspend to disk.
