Step 1 use the loop option to generate an audio sample long enough.
avconv -loop ... -i ... -c:a something audio.ts
Step 2 merge the two audio, the in.something is the shortest
avconv -i audio.ts -i in.something -af ... -c:a copy out.mkv
In a single step:
avconv -loop ... -i ... -c:a something -f mpegts - | avconv -i - -i
This is untested but should work.
