Enquanto digito isso, no meu sistema Netrunner Debian 12 KDE, se eu clicar, por exemplo, em Ctrl- Alt- F3, será exibido um prompt de login de terminal.

  • Não consigo passar desse prompt. Se eu digitar o nome de usuário e a senha corretamente, ele simplesmente limpa a tela e mostra o prompt de login do terminal novamente.
  • Ainda posso voltar para a GUI usando Ctrl- Alt- F7para continuar digitando esta pergunta.

Alguma sugestão de onde procurar?

  • /var/log/syslogcontém isso depois de fazer isso:

Sou novo no ices2 e no icecast2, mas consegui configurar um stream onde posso me ouvir em meus fones de ouvido. Então, algum sucesso básico com o sistema. Agora, o verdadeiro objetivo:

Gostaríamos de transmitir em 8 idiomas diferentes usando os recursos de interface de áudio de um gravador Zoom R16. Fazendo arecord --dump-hw-params hw1,0no R16, ele retorna:

Recording WAVE 'hw1,0' : Unsigned 8 bit, Rate 8000 Hz, Mono
HW Params of device "default":
--------------------
ACCESS:  RW_INTERLEAVED
FORMAT:  U8 S16_LE S16_BE S24_LE S24_BE S32_LE S32_BE FLOAT_LE FLOAT_BE MU_LAW A_LAW S24_3LE S24_3BE
SUBFORMAT:  STD
SAMPLE_BITS: [8 32]
FRAME_BITS: [8 1024]
CHANNELS: [1 32]
RATE: [1 384000]
PERIOD_TIME: (2 4294967295)
PERIOD_SIZE: [1 1398102)
PERIOD_BYTES: [128 1398102)
PERIODS: [3 1024]
BUFFER_TIME: (7 4294967295]
BUFFER_SIZE: [3 4194304]
BUFFER_BYTES: [384 4194304]
TICK_TIME: ALL
--------------------

Pergunta 1: Qual é o significado dos números com espaços entre eles, como SAMPLE_BITS: [8 32]? Isso significa que os bits de amostra podem ser 8, 16 ou 32?

Pergunta 2: Como resolver "EROR input-alsa/alsa_open_module Formato de exemplo não disponível: argumento inválido"

Quando tento iniciar o ices2, ele simplesmente fecha e o log diz:

[2023-12-10  20:48:46] INFO ices-core/main IceS 2.0.3 started...
[2023-12-10  20:48:46] EROR input-alsa/alsa_open_module Sample format not available: Invalid argument

[2023-12-10  20:48:46] INFO ices-core/main Shutdown complete

O arquivo de configuração que estou usando para ices2 é:

<?xml version="1.0"?>

        <!--    Input module.

            This example uses the 'alsa' module. It takes input from the
            ALSA audio device (e.g. line-in), and processes it for live
            encoding.  -->
        <input>
            <module>alsa</module>
            <param name="rate">48000</param>
            <param name="channels">8</param>

            <param name="periods">2</param>
            <!-- Read metadata (from stdin by default, or -->
            <!-- filename defined below (if the latter, only on SIGUSR1) -->
            <param name="metadata">1</param>
            <param name="metadatafilename">testES</param>
        </input>

        <!--    Stream instance.

            You may have one or more instances here.  This allows you to
            send the same input data to one or more servers (or to different
            mountpoints on the same server). Each of them can have different
            parameters. This is primarily useful for a) relaying to multiple
            independent servers, and b) encoding/reencoding to multiple
            bitrates.

            If one instance fails (for example, the associated server goes
            down, etc), the others will continue to function correctly.
            This example defines a single instance doing live encoding at
            low bitrate.  -->

        <instance>
            <!--    Server details.

                You define hostname and port for the server here, along
                with the source password and mountpoint.  -->

            <hostname>localhost</hostname>
            <port>8000</port>
            <password>hackme</password>
            <mount>/spanish.ogg</mount>
            <yp>1</yp>   <!-- allow stream to be advertised on YP, default 0 -->

            <!--    Live encoding/reencoding:

                channels and samplerate currently MUST match the channels
                and samplerate given in the parameters to the alsa input
                module above or the remsaple/downmix section below.  -->

            <encode>  
                <quality>0</quality>
                <samplerate>24000</samplerate>
                <channels>8</channels>
            </encode>

            <!-- stereo->mono downmixing, enabled by setting this to 1 -->
            <downmix>0</downmix>

            <!-- resampling.
            
                Set to the frequency (in Hz) you wish to resample to, -->
             
            <resample>
                <in-rate>48000</in-rate>
                <out-rate>24000</out-rate>
            </resample>
        </instance>

    </stream>
</ices>

Mas no geral, o que eu gostaria de saber é:

Pergunta 3: O que precisa ser inserido no arquivo de configuração para que o canal 1 do gravador possa ser transmitido em espanhol, o canal 2 em francês, o canal 3 em alemão, ... canal 8. Presumo que realmente precise de 8 configurações diferentes arquivos e execute 8 instâncias do ices2, mas como selecionar o canal certo?

Editar: posso dizer também que isso funciona para gravar um arquivo wav de 8 canais:

arecord -D hw:1,0 -f S32_LE -r 48000 -c 8 testr16.wav
