Konten pada halaman ini bergantung pada hardware. Pilih dari opsi berikut:
Sebelum menjalankan sampel, Anda harus mengkonfigurasi sistem audio pada
{i>Raspberry Pi.<i}
Temukan perangkat perekaman dan pemutaran.
Temukan lokasi mikrofon USB Anda dalam daftar perangkat hardware perekaman. {i>Write<i}
nomor kartu dan nomor perangkat.
arecord -l
Temukan speaker Anda dalam daftar perangkat hardware pemutaran. Tulis
nomor kartu dan nomor perangkat. Perhatikan bahwa colokan 3,5 mm biasanya
berlabel Analog atau bcm2835 ALSA (bukan bcm2835 IEC958/HDMI).
aplay -l
Buat file baru bernama .asoundrc di direktori utama (/home/pi). Merek
memastikannya memiliki definisi {i>slave <i}yang tepat untuk mikrofon dan {i>speaker<i}; gunakan
konfigurasi di bawah tetapi ganti <card number> dan <device number> dengan
angka yang Anda
tulis di langkah sebelumnya. Lakukan ini untuk pcm.mic
dan pcm.speaker.
Tekan tombol panah atas untuk menyetel level volume pemutaran ke sekitar 70.
Putar suara uji coba (suara ini adalah orang yang berbicara). Tekan Ctrl+C saat
selesai. Jika Anda tidak mendengar apa pun saat menjalankan ini, periksa speaker Anda
koneksi jarak jauh.
Periksa rekaman dengan memutar ulang. Jika Anda tidak mendengar
apa pun, Anda mungkin
perlu memeriksa volume rekaman di alsamixer.
aplay --format=S16_LE --rate=16000 out.raw
Jika perekaman dan pemutaran berfungsi, berarti Anda telah selesai mengonfigurasi audio.
Jika tidak, periksa apakah mikrofon dan speaker terhubung dengan benar. Jika
mungkin ini bukan masalahnya, coba gunakan mikrofon atau speaker lain.
Ingatlah jika Anda memiliki monitor HDMI dan speaker colokan 3,5 mm
terhubung, Anda dapat memutar audio dari salah satunya. Jalankan perintah berikut:
sudo raspi-config
Buka Advanced options > Audio, lalu pilih perangkat output yang diinginkan.

Then create `.asoundrc` file and update it with specific hardware details. Users then verify audio functionality by adjusting volume using `alsamixer`, testing playback with `speaker-test`, and testing recording using `arecord` and `aplay`.
