No analogue audio output, digital output ok

Asked by Adrian Norman on 2018-02-11

Hi,

I am new to Ubuntu, but have just installed 16.04.03 on an old P4 System.

The machine is a HP DC5100MT which has a built-in analogue speaker (the Outputs from the on-board sound card are working fine).

Under Windows I had to install the AC'97 Audio Driver designed for Vista for the speaker to work; if the Audio Driver was updated to the SOUNDMAX Driver, then the speaker would no longer work.

Under Ubuntu, clicking on the Speaker Icon and entering Sound Settings I have 3 Devices listed:

1. Digital Output (S/PDIF)
2. Headphones / No Amplifier
3. Headphones / Amplifier

AlsaMixer shows:

Card: Intel ICH6
Chip: Analog Devices AD1981B

I have set the Master Mono & Aux to 100% Volume, and made sure that they are not muted.

selecting the Sound Card (F6) I am given 3 options:

1. - (default)
2. 0 Intel ICH6
3. Enter device name...

Any pointers would be appreciated.

Ok,

I don't know what happened, but it just started working on it's own accord...
