Pessoal:

Um grande abraço à toda a comunidade.

Estou tentando fazer funcionar um stream de áudio em meu linux, mas não consigo.

Baixei o icecast2, o darkice, assim como o lame e as libs necessárias.
Compilei tudo e instalei.
Ontem, por algum milagre, até funcionou, mas agora parou de capturar o áudio.
Explico:
Uso o aumix para controlar a entrada de áudio pela entrada microfone da placa de som. O áudio aparecenas caixas de som, sem problemas. Se eu uso o mocp para ouvir músicas, funciona também, ou seja, a placa de som funciona e o aumix consegue controlar a entrada do microfone.
Muito bem, os daemons icecast2 e darkice estãop rodando aparentemente sem erros.
Se eu acesso minha máquina, na porta do icecast2 (8100 - foi a que eu usei), usando uma máquina windows, ele apresenta a tela com o ponto de montagem do áudio. Quando clico no link desta página para ouvir o áudio, é aberto o media player do windows e ele começa a receber o stream mas não tem áudio (na verdade ele conecta, mas não diz nada que está buferizando).

abaixo, meus arquivos de configuração:

icecast.xml:

<!-- If enabled, this will provide a burst of data when a client
first connects, thereby significantly reducing the startup
time for listeners that do substantial buffering. However,
it also significantly increases latency between the source
client and listening client. For low-latency setups, you
might want to disable this. -->
<burst-on-connect>1</burst-on-connect>

specific on how much to burst. Most people won't need to
change from the default 64k. Applies to all mountpoints -->

Agora, o darkice.cfg:

Alguém tem algua sugestão?

Já estou perdendo o resto dos cabelos que me sobram...

Obrigado a todos.
