audio card C230 not detected Ubuntu 20.04



I run Ubuntu 20.04 on my computer equiped with a C230 chip for the audio. But it looks like the card can not be detected properly. I can not get an analog/digital profile autodetected. Only HDMI profiles are available. It looks like the card is not properly recognized by Ubuntu.Sound is not working on loadspeaker. Have to connect an external TV through HDMI.

Could you help please?

Hello @MarcFran

Thank you for posting on the Intel® communities.

In order to provide you with the proper information, could you please confirm the full/exact brand and model of your computer or motherboard? Is this regarding an Intel® Serer or an Intel® NUC?

Best regards,

Hi Andrew, this is a laptop, Acer Aspire V5-V591. Here are the details. Could you help?

I have tried to look at how the intel hardware is detected by Ubuntu - especially the C230, but i am not sure how it is being supported.

Advise would be welcome,

Hello MarcFran

Thank you for the information provided.

We are still checking this and we would like you to confirm some additional details:

1- Just to make sure, this "audio card C230" is the one that works through "3.5mm jack" connectors on the computer? For instance, where you plug headphones/speakers. Is this correct? If not, could you please provide more details?

2- Could you please confirm what is the exact model of the Intel Chipset in the computer? We were looking for this information but we were not able to find it on the Acer* website.

3- Have you checked this with UBUNTU* Support? For instance, checking UBUNTU* Forums we see topics that might relate to this topic: Ubuntu 20.04 - No sound.

Please note that audio functionality through audio jack connectors (if this is the one you are using) also depends on the customizations performed by the computer manufacturer (OEM) and we would not be aware of those customizations so it is also recommended to check this further with your OEM Acer*.

hi Andrew,


Yes the C230 card is the one that works with the audio jack and loud speaker. What ever I do i got only a dummy device. I can not get the computer to recognize an other output other than the dummy one and the HDMI.

Here is the output of the alsa diag.

I have been checking all possible Ubuntu and Linux forums for weeks now. Nothing works. I have logged a ticket in but despite all advises no solution has been found so far. I have upgraded Ubuntu on 20.1 just in case. I am really running out of options. I would like to know how to get the sound card recognized as a physical output.

Hello MarcFran

Thank you for your response.

After checking this further, it is worth mentioning that we only provided Intel® Chipset Software and related links to drivers for Intel® Server Boards, Intel® Server Systems, and Intel® NUCs. For pre-built systems or third-party motherboards, the recommendation is to contact the Original Equipment Manufacturer for the latest updates and technical support information, in this case, ACER* Support. This recommendation is also important considering the previous facts we shared regarding that we would not be aware of the customizations performed by the OEM Acer*, so the ones that handle all the technical information and should provide the proper assistance is your OEM. At this point, the best channel of support is through Acer*.

Having said that, we will proceed to close this inquiry now. If you need any additional information, please submit a new question as this thread will no longer be monitored. Thank you for your understanding.

Best regards,
