Update 3 : Debian on the 11,1 model MacBook Pro 13
To resume, here are the previous posts :
The last week end, I’ve resolved flash problems which were not in fact due to flash as I thought but to the Alsa driver. It wasn’t charging the proper the drivers in the correct order. That’s why MID card was used before PCH. So I wasn’t able to listen anything and that’s why Youtube videos didn’t worked.
First of all, look at the correct order of your sound card :
$ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xb0a14000 irq 69 1 [MID ]: HDA-Intel - HDA Intel MID HDA Intel MID at 0xb0a10000 irq 68
Here it’s correct as index 0 is my PCH card and 1 is my MID (but it was inverted). To correct it, I’ve updated line in /etc/modprobe.d/alsa-base.conf to :
options snd-hda-intel model=mbp101 index=1
Then rebooted and now it’s ok :-). I hope this will help you too. The remaining things are disabling S/PDIF (should be corrected in 3.13 kernel) and the webcam (no news :-().
