FreeBSD：スピーカーのサウンドと内蔵ヘッドフォンジャックの自動切り替えなし
Lenovo Ideapad 100S 14インチIBR-14インチIntel Celeron CPU N3060 @ 1.60 GHz、32 GB SSD、4 GB RAM、Realtek ALC269をチップサウンドとして使用しています。
マシンはFreeBSD 12.0を実行しています。内蔵スピーカーとヘッドフォンジャックのサウンドを正常にセットアップできました。しかし、それらを自動的に切り替えるのに問題があります。
切り替えのために私は実行します：
スピーカーをアクティブ化するには（および起動時にも実行します）：
Sudo sysctl hw.snd.default_unit=1
ヘッドフォンの音を有効にする場合：
Sudo sysctl hw.snd.default_unit=0
Default_unitを変更しない場合、デフォルトで0になります。これは、このモデルのヘッドフォンジャックです。
必要に応じて、内蔵スピーカーからヘッドフォンへの自動移行に成功したと聞いています。
現時点では、私が言ったように、私は手動で内蔵スピーカーまたはヘッドフォンを通して音を出しています、そしてそれはそのように設定されています：
/boot/loader.conf
# load sound driver
snd_hda="YES"
# load mixer
mixer_enable="YES"
sound_load="YES"
# Minimize the number of interrupts from the sound card
hint.pcm.0.buffersize=65536
hint.pcm.1.buffersize=65536
hw.snd.feeder_buffersize=65536
hw.snd.latency=7
/etc/sysctl.conf
# Without this sound does not even work, both in speakers or headphones
dev.hdac.0.polling=1
# Sound for speakers when booting
hw.snd.default_unit=1
私はまた、ヘッドフォンの切り替えを設定するために使用しようとしました：
/boot/loader.confに追加：
# Out : speaker + headphones
hint.hdac.0.cad0.nid25.config="as=1 seq=15"
/boot/devices.hintsに追加：
hint.hdaa.0.nid20.config="as=1 seq=0 device=Speaker"
hint.hdaa.0.nid21.config="as=1 seq=15 device=Headphones"
そしてまた：
hint.hdaa.1.nid20.config="as=1 seq=0"
hint.hdaa.1.nid21.config="as=1 seq=15 device=Headphones"
また、/etc/sysctl.confに追加してみました。
hw.snd.default_auto=1
ヘッドフォンからスピーカーに切り替えるための変更は成功しませんでした。
今のところアイデアはありません、何か提案はありますか？

リファレンス： man snd_hda FreeBSD 12.
LenovoでFreeBSDを使用するようになりました。現在はFreeBSD 12.0を使用しています。前の答えは、完全に正しいわけではありませんが、私を正しい方向に導きました。
サウンドを機能させるには、ボックスから取り出し、ヘッドフォンに切り替えて、オーディオジャックに挿入します。
- ディレクティブhw.snd.default_unitを
sysctl.confから取り出す必要があります。 - デフォルトのas/audiosetは2なので、1ではなく2を使用する必要があります。
as=1を試しましたが、意図したとおりに機能しません。
デフォルトのsysctl目視検査、質問/以前の投稿、および@Trevorの回答に基づいて、サウンドを機能させるためのLenovo Ideapad 100S IBRを取得し、自動的にヘッドフォンに切り替えるための完全な構成は次のとおりです。
ファイル：/etc/sysctl.conf
# Without this sound does not even work, both in speakers or headphones
dev.hdac.0.polling=1
ファイル：/boot/loader.conf
snd_hda_load="YES"
mixer_enable="YES"
sound_load="YES"

PS。文書化のみを目的としたデフォルトのシステム構成は次のとおりです。

入力すると：
Sudo sysctl hw.snd.default_unit=1
または
Sudo sysctl hw.snd.default_unit=0
Pcm1とpcm0を切り替えています
Dmesgの出力を見ると、「Playback：」の下で、pcm0とpcm1の両方が階層のように見えます。
line 124: pcm0: nid=21 [pin: Headphones (Black Jack)]
pcm0: + <- nid=12 [audio mixer] [src: pcm, mix]
pcm0: + <- nid=2 [audio output] [src: pcm]
pcm0: + <- nid=11 [audio mixer] [src: mix]
line 200: pcm1: nid=20 [pin: Speaker (Fixed)]
pcm1: + <- nid=13 [audio mixer] [src: pcm, mix]
pcm1: + <- nid=3 [audio output] [src: pcm]
pcm1: + <- nid=11 [audio mixer] [src: mix]
* nid = 21のヘッドフォン（nid = 12、nid = 2、＆nid = 11にマップ）
* nid = 20のスピーカー（nid = 13、nid = 3、＆nid = 11にマップ）
BSDがそれらの間でauto-switchにするには、両方が同じ（a）udio（s）etのメンバーである必要があります。
"as = 1"audio set equals one
"seq"sequence序数（0,1,2、... 15）
/boot/device.hintsを編集する以前の試み
[ERROR!!] hint.hdaa.0.nid20.config="as=1 seq=0 device=Speaker"
[CORRECT] hint.hdaa.0.nid21.config="as=1 seq=15 device=Headphones"
そしてまた：
[CORRECT] hint.hdaa.1.nid20.config="as=1 seq=0"
[ERROR!!] hint.hdaa.1.nid21.config="as=1 seq=15 device=Headphones"
覚えておいてください：
*the Headphones are on pcm0 (pcm0) = hint.hdaa.0
*the Speaker is on pcm1 (pcm1) = hint.hdaa.1
ソリューション：「as」キーワード引数を使用して、同じ（a）udio（s）etに配置します。
/boot/device.hints
hint.hdaa.1.nid20.config="as=1 seq=0"
hint.hdaa.0.nid21.config="as=1 seq=15 misc=0"
「misc = 0」は不要かもしれません。ハードウェア固有だと思います。
