Salut, tinc una debian 10.3 en un portàtil thinkpad X220 i no em funciona la captura d'àudio. Tinc un micro intern que m'ha funcionat durant força temps i ara m'ha deixat de funcionar. El problema és que no recordo des de quan ni què hi vaig fer que li afectés. Un altre tema és que només té una entrada d'àudio, per micro i cascos simultàniament, i sembla que ho detecta bé, perquè quan hi endollo uns cascos amb micro integrat el pavucontrol detecta que tinc un micro connectat. He provat el alsamixer, el pavucontrol i el volum del lxde i no he trobat que tingui res amb mute. De fet, el pavucontrol quan surt el volum del micro, en altres màquines veus les ratlletes que es mouen a mesura que parles, i pots clicar a mute i es paren. Però en el meu cas, no surten ni les ratlletes. Primer he pensat que era un problema de hardware i que el micro intern no funcionava, però quan he vist que connectant els cascos amb micro tampoc no gravava, crec que tinc en algun lloc la captura a 0.
Em trobo amb la mateixa situació també Debian 10.3 però amb un Elitebook 830 G6 (amb nucli 5.5.11). He trobat d'altres usuaris (Ubuntu, però) en la mateixa situació...
Amb el nucli 5.4.0-0.bpo.4-amd64 del mateix Debuan passa el mateix.
Algunes proves que potser pots fer:
$ lspci |grep audio 00:1f.3 Multimedia audio controller: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 11)
$ sudo lspci -v -s 00:1f.3 00:1f.3 Multimedia audio controller: Intel Corporation Cannon Point-LP High Definition Audio Controller (rev 11) Subsystem: Hewlett-Packard Company Cannon Point-LP High Definition Audio Controller Flags: bus master, fast devsel, latency 64, IRQ 130 Memory at 4022108000 (64-bit, non-prefetchable) [size=16K] Memory at 4022000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_skl
Així que el controlador és snd_hda_intel.
Una crida al programa alsa-info (paquet alsa-utils) també aporta moltíssima informació.
(en el meu cas he trobat que la targeta en realitat és una Realtek ALC215.
Llàstima que amb això del confinament no pugui mirar-ho en el thinkpad X220 perquè el tinc a la feina...
SALUT!
Josep
Em podeu ajudar? Merci. Vinga, Salut i desobediència! Enric.
