Review: Funciona Perfectamente - Compré este adaptador para conectar mi barra de sonido Sonos Ray al PC y la verdad es que cumple perfectamente con su función. La instalación fue muy sencilla: lo conecté y funcionó al instante, sin necesidad de configuraciones complicadas. La calidad de sonido es excelente, no he notado pérdidas ni interferencias. Se nota que transmite bien la señal y permite aprovechar al máximo la barra de sonido. Además, es un accesorio compacto y ligero, fácil de llevar o guardar. En resumen, un producto práctico, fiable y totalmente recomendable si necesitas una solución para conectar por óptico desde un puerto USB.
Review: Funciona bem em 48khz, trava em 192khz depois de um tempo. - Funciona mais ou menos. No modo 192khz ele as vezes trava, fica distorcido. No modo 48khz ele funciona sem problemas. Não sei se é problema no firmware dele, não sei se tem como atualizar, no manual não tinha nenhuma informação sobre isso, eu busquei informacao e diz que nao tem, entao o problema pode ser permanente.
