With some headphones and earphones, the sound output is distorted, e.g. the left and right channels are swapping constantly, this issue is especially serious with human speech. I used a Sony MDR-AS800AP earphone directly inserted to the sound card's audio output, the sound is distorted. However, if I hold the button on the earphone the output is normal but at a higher volume. I can confirm that the earphone and the sound card have no problem because it plays normally on an Android smartphone or on dual-booted Windows. The problem is certainly in ALSA. I also tested with other earphones, some of them have similar problems. Some earphones have an "Android/Apple" switch, and the distortion happens when the switch is set to "Apple". I am using ALSA directly without PulseAudio or other Poetterware. The configuration can be found in the attachment. ---END OF MESSAGE--- Please reply to this e-mail with UTF8-encoded plain text.
