&nbsp; Estimados, trabajamos muy bien con el Ubuntu 18.04 durante dos a&ntilde;oscon el chip Via 1705 sin problemas, com un sonido refinado em caja de sonido Harman/Kardon, lamentablemente al actualizar para Ubuntu 20,04 el sonido no se escucha, intentamos todos los pasos indicados en el link https://help.ubuntu.com/community/SoundTroubleshootingProcedure, pero no resolvio. 
&nbsp; Nos agrad&oacute; el nuevo Ubuntu 20.04, por favor una soluci&oacute;n para no desistir de este. Gracias. 
 
&nbsp; Bom, para que fique bem claro, este &eacute; um equipamento com o que 
&nbsp; trabalho em varias regi&otilde;es, por isso se houver algum colegas que 
&nbsp; entenda um destes idiomas, agradeceria uma solu&ccedil;&atilde;o, trabalhamos 
&nbsp; durante dois anos com um chipset Via 1705 num Ubuntu 18.04, ao 
&nbsp; atualizar para a nova vers&atilde;o Ubuntu 20.04 nos deparamos em que o som 
&nbsp; n&atilde;o funciona, a placa n&atilde;o &eacute; detectada pelo painel GUI das 
&nbsp; configura&ccedil;&otilde;es do Gnome, e pelo terminal o pulseaudio n&atilde;o funciona. 
&nbsp; Favor indicar uma solu&ccedil;&atilde;o pois o resto do sistema est&aacute; est&aacute;vel e 
&nbsp; funcionando, n&atilde;o queremos desistir da atualiza&ccedil;&atilde;o. Obrigado
