I'm using a Swissonic USB Studio.
With an older CVS version (from around 29th June), playback and capture
were pretty much OK, except for a ticking (the repetitive peaks issue?)
and some noise. Using the latest CVS version:
aplay -D studio /mnt/spare/music/test.wav
Playing WAVE '/mnt/spare/music/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Stereo
aplay: set_params:737: Broken configuration for this PCM: no configurations available
ecasound and jackd die with less descriptive error messages.
The error comes from a call
err = snd_pcm_hw_params_any(handle, params);
on line 735 of aplay.c
The output from /proc/asound/card1/stream0 is

Any help much appreciated.
BTW, what does Format: STD mean?
