[SATELLITE P850, Realtek ALC280, Speaker, Internal] No sound at all from built-in speakers; headphones work OK

[Federico Linares]

Hello,

this is a duplicate for bug#1023593 which in turn, is very similar to bug# 1008969

I decided to duplicate the bug using the tool "ubuntu-bug audio", and having it collecting all the system information and adding it to the report. I hope I did the right way; otherwise I apologize for my lack of experience on reporting bugs. I hope next time I'll do it properly following your recommendations.

I copy & paste the inicial bug#1023593 text description:

I have tried to apply the patch povided in bug:

Any help would be greatly appreciated. Many thanks in advance.

Status changed to 'Confirmed' because the bug affects multiple users.

[Waraqa (waraqa)]

I have the same problem on Toshiba Satellite P850-B236
I hope that this bug will be resolved quickly since audio playback in headphone and recording are working fine.
