Jabra BIZ 2400 USBヘッドセットをDebian Jessieインストールで動作させようとしていますが、ヘッドセットから何も得られません。
テストのためにAudacityをインストールしました。ただし、「テスト1、2、3、「テスト」と呼ばれる期間は3秒間続きます。
~からXTronics WikiのDebianサウンドインストールするには、次のことをお勧めします。
apt-get install alsa-base alsamixergui alsa-oss alsaplayer-alsa alsaplayer-common
alsaplayer-gtk alsaplayer-oss alsa-tools alsa-tools-gui alsa-utils bluez-alsa
gstreamer0.10-alsa libsox-fmt-alsa jackd jackd2 jackeq jack-rack jack-stdio
jack-tools pulseaudio-module-jack qjackctl qjackrcd slv2-jack vlc-plugin-jack
pulseaudio pulseaudio-esound-compat pulseaudio-module-gconf
pulseaudio-module-jack pulseaudio-module-x11 pulseaudio-module-zeroconf
pulseaudio-utils vlc-plugin-pulse pavucontrol
これにより、オーディオ/ビデオ設定からすべての「基本デバイス」選択が削除され、PulseAudio Sound Serverに置き換えられ、追加タブ「オーディオハードウェア設定」がハードウェアおよびデジタルステレオ出力/アナログモノチャンネルの入力と再生からJabra BIZ 2400 USBを選択します。 （Jabra BIZ 2400 USBデジタルステレオ/デジタル出力（S / PDIF））。
ただし、テストボタン（左前/右前）は何もしません。
どんなアイデアでも可能です。
