Move custom ttable with equal channels case from a separate ttable_last exception into a common plugins insertion loop. Fixes plug with ttable for float pcms (jack, ladspa). Example: aplay -fFLOAT_LE /dev/zero pcm.!default { type plug slave.pcm { type null } ttable.0.0 1 } --- src/pcm/pcm_plug.c | 36 +++++++++++------------------------- 1 file changed, 11 insertions(+), 25 deletions(-)
