The following changeset by Hartmut did fix this for all above cards. changeset: 7186:eb6bc7f18024 parent: 7182:3a880d2669a6 user: Hartmut Hackmann <hartmut.hackmann@xxxxxxxxxxx> date: Sun Feb 10 00:54:24 2008 +0100 summary: tda10086: make the 22kHz tone for DISEQC a config option Here is Hartmut's fix, mercurial changeset 7186, acked by Patrick and Oliver, against 2.6.24.4.
