Audacity não funciona mais com pulseaudio

  • 772

ATUALIZAÇÃO: A atualização de hoje para alsa-lib-1.1.7-2corrigir o problema. (23/11/2018)

Arch Linux, atualizado. Como tantas vezes, uma -Syuatualização quebrou as coisas novamente. Desta vez é audácia. Normalmente audacity, e qualquer outro aplicativo de reprodução/gravação apareceria em pauvcontrol- Não é mais audácia. Eu poderia usar pauvcontrolpara escolher o coletor e a fonte da qual desejo gravar ou reproduzir áudio usando o audacity - não mais.

Nas preferências do audacity, ele diz apenas ALSAno menu suspenso superior, não tenho certeza se deveria ser assim ou se disse PulseAudioantes. Nem todos os meus dispositivos estão na guia de reprodução. O mesmo vale para a seleção do dispositivo de gravação, mas o dispositivo de loopback do qual preciso gravar está lá, então funciona.

preferências

Mas agora eu queria reproduzir o som do audacity também e simplesmente não funciona mais. Ele não lista meu dispositivo de reprodução USB e, quando o configuro, sysdefaultapenas recebo um erro.

$ pulseaudio -v
pulseaudio 12.2

$ audacity --version

Não tenho certeza se esses avisos significam alguma coisa, ele não imprimirá a versão.

Mesmo que eu não tenha certeza se esses erros são por causa do ALSA e talvez completamente não relacionados ao problema do PulseAudio.

    Nos fóruns eu encontrei esse bug . Este é um problema com a versão mais recente (1.1.7) do alsa-lib. Fazer o downgrade para sua versão anterior deve resolver o problema por enquanto:

    pacman -U /var/cache/pacman/pkg/alsa-lib-1.1.6-1-x86_64.pkg.tar.xz

  2. Estou executando 1.1.8-1 de alsalibs e tive um problema semelhante. Iniciar o audacity mudou minha saída para o alto-falante interno. Eu consegui trabalhar com alsactl restore, então pulseaudio -k, mas é wonkey. VLC e audácia não parecem usar a saída ao mesmo tempo.
