I upgraded from Wheezy to Stretch (via Jessie, via Jessie) and lost sound in the process. I have two sound devices--HD-AUDIO GENERIC (which corresponds to HDMI) and HDA ATI SB (Realtek chip which I use for sound output). Selecting the HDA ATI SB card in alsamixer (F6) was fruitless (although you can eventually unmute muted channels there to positive effect). I installed pavucontrol, and in the Configuration tab turned the HDMI profile off and the analog duplex output which corresponds to my Realtek chip on. As I have no speakers, in Output Devices I selected headphones (I do have headphones). I now have sound through the headphones. -- “Be yourself; everyone else is already taken.” -Oscar Wilde
