Hi,

I have a Pi5 with 8GB on which I installed debian 12 and Home assistant.
Till approx. 15 or March it was working great with my samsung TV using HDMI.
However it has been 2 weeks videos from browser are slow and there is no sound at all.
It looks like some codec issue, however there is no sink on wpctl status report except the dummy output.
However the aplay -l command returns:

Code:

**** List of PLAYBACK Hardware Devices ****card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]  Subdevices: 0/1  Subdevice #0: subdevice #0card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]  Subdevices: 1/1  Subdevice #0: subdevice #0
and amixer info returns:

Code:

Card default 'pulse'/'PulseAudio'  Mixer name    : 'PulseAudio'  Components    : ''  Controls      : 4  Simple ctrls  : 2
I wounder where went the HDMI audio output :(

so what's going wrong with updates ?

thank you
