@Lin I carried out a new test starting with the thinkpad_acpi module unloaded first: the mute button works when the thinkpad_acpi module is loaded with the option enable=0 (but for the internal speakers only as without the thinkpad_acpi module unloaded).
These are the command sequence I've typed at the terminal: > sudo rmmod thinkpad_acpi > sudo modprobe thinkpad_acpi enable=0 > lsmod | grep think thinkpad_acpi 67659 0 nvram 6342 1 thinkpad_acpi snd 49006 14 thinkpad_acpi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device led_class 2633 2 thinkpad_acpi,sdhci , and next I test the button with the hereabove outcome (successfull).
