Python3 pyalsaaudio "Deprecated setchannel, setformat, setrate and setperiodsize"

Question

Im just in the process of updating some python programs to work on Python3. One of these uses Alsa Audio and according to their github entry, version 0.9.0 includes:

Pyalsaaudio 0.9.0

Added keyword arguments for channels, format, rate and periodsize Deprecated setchannel, setformat, setrate and setperiodsize

I have some code along the lines of that below which uses the deprecated stuff but Im not sure how to re-write it! Any ideas would be most welcome

    output = aa.PCM(aa.PCM_PLAYBACK, aa.PCM_NORMAL)
    output.setchannels(no_channels)
    output.setrate(sample_rate)
    output.setformat(aa.PCM_FORMAT_S16_LE)
    output.setperiodsize(chunk)

Answer 1

I had the same problem. As of alsaaudio Version 0.9.0 keyword arguments were added for channels, format, rate and periodsize. The code above can be written as follows.

output = aa.PCM(aa.PCM_PLAYBACK, aa.PCM_NORMAL,
                channels = no_channels,
                rate = sample_rate,
                format = aa.PCM_FORMAT_S16_LE,
                periodsize = chunk)
