swift 05/04/24 09:14:23 Modified: xml/htdocs/doc/en alsa-guide.xml Log: ALSA sometimes shows channels of which you can not change the volume. If you unmute those channels, it'll force the regular channels to not provide any sound anymore. The user must leave these channels muted. Thanks to Rickard Lindgren <[EMAIL PROTECTED]> for noticing, confirmed by Martin Schmeisser. The reason: most of the time, these channels provide a different output; enabling them disables the normal output. For instance, IEC985 unmuting disables regular output in favor of S/PDIF.
