When I try to play anything with aplay i get the result below.

aplay -D plughw:1,0 /media/E/Musica/Dire\ Straits\ -\ Brothers\ In\ Arms\ \(Re-Mastered\ 1996\)\ EAC\ Flac\ Level\ 8/Dire\ Straits\ -\ 01\ -\ So\ Far\ Away.flac
Playing raw data '/media/E/Musica/Dire Straits - Brothers In Arms (Re-Mastered 1996) EAC Flac Level 8/Dire Straits - 01 - So Far Away.flac' : Unsigned 8 bit, Rate 8000 Hz, Mono
aplay: set_params:1145: Unable to install hw params:
ACCESS:  RW_INTERLEAVED

SUBFORMAT:  STD
SAMPLE_BITS: 8
FRAME_BITS: 8
CHANNELS: 1

PERIOD_BYTES: 1000
PERIODS: 4
BUFFER_TIME: 500000
BUFFER_SIZE: NONE
BUFFER_BYTES: 4000
TICK_TIME: 0

I tried configuring .asoundrc as follows, because the output aplay says channels 1 but channels still says 1:

pcm.rp {
    type plug
    slave {
        pcm "hw:1,0"
        channels 2
    }
}

I need a pointer on what to look at to get this config working.
thanks
