[Risolto] 14.04 Audio 'salta' durante la riproduzione

[coldpatrix]

Ciao a tutti,

durante la riproduzione di un file audio, molto spesso l'audio 'salta' e non è uniforme nella sua riproduzione. Cosa può essere?

[Mdfalcubo]

Senza dare nessuna info sul pc e sulla versione di ubuntu la vedo dura...

[coldpatrix]

Hai ragione... ho Ubuntu 14.10. Credo che sia un discorso relativo ad Alsa e PulseAudio, il quale affligge la mia macchina da sempre. Mi piacerebbe trovare il modo di utilizzare la migliore configurazione audio possibile e senza intoppi...

Se vuoi dare qualche info sul pc

sudo lshw

La 14.10 è fuori supporto ...

Sposto in multimedia. Installa una versione più recente, se si ripresenta lo stesso problema vedremo di affrontarlo più nello specifico.

Scusate, è la 14.04...

Ecco la risposta alla stringa:

Gli " ubuntu-restricted-exras " li hai installati ?

[Mdfalcubo]

Posta anche una schermata di alsamixer. Il problema lo hai su un singolo file audio o su tutti i file audio che provi a riprodurre?

[coldpatrix]

Gli 'ubuntu-restricted-extras' sono installati. Il problema si pone su vari files e non sono su uno singolo, anche utilizzando diversi software.

Come posto una schermata di alsamixer?

[Mdfalcubo]

Dai

Codice: Seleziona tutto

alsamixer

nel terminale e posti uno screenshot/immagine.

Ho notato inoltre che il problema avviene quando di solito c'è un aumento di consumo di RAM...

[coldpatrix]

Nessun aiuto?

[coldpatrix]

Ho risolto cambiando il governor della CPU su 'performance'.
