    Hi all,

    I recently experienced a receiving problem with my APRS equipment. (It
    is an old desktop comp with a new installation of Debian 8 with Mate
    GUI, integrated sound card, as well as a secondary PCI sound card I
    added later to locate the issue, Rigblaster Plug&Play modem interface,
    and a Chinese walkie radio.)

    The cable from Rigblaster is connected to the ext spk/mic connectors of
    the radio. The problem is when all parts are wired together, the radio
    somehow becomes 'deaf', i.e. it does not show any sign of incoming
    reception. No reception at all. But as soon as the cable is pulled out,
    the radio recovers and RX normally. I don't have any clue what might be
    wrong. By the way, the radio sends beacons to the air (tested under Direwold/Xastir), so it seems that the TX part is just fine.

    Interestingly, all works well when a laptop is used instead of the
    desktop. The laptop has its integrated sound card.

    The only difference in between the desktop and the laptop is the timing
    and probably content of the installed OS. The laptop was installed
    several years ago with Debian 6 incl. Gnome, KDE, Mate, ..., then
    gradually upgraded via Debian 7, to Debian 8 now.

    On the other side, the desktop was installed recently with Debian 8
    (with Mate) because previous iterations of Debian disappeared from
    archives as not supported any more.

    It also seems that similar issues I have at some other desktop machines
    that also started as Debian 6 and became Debian 8 over time. But not on
    the laptop. It works well in APRS. Any similar experience or idea what
    to do?
