voice volume adjustment with interactive command line does not work with Raspberry pi

[royjiang]

hi, installed douban.fm in my rpi , everything works fine except the volume adjustment using "=" and "-" does not work , here is the fix i verified.

the reason is in the douban.py there is a line of code to associated to amixer "Master", but RPi does not use "Master" , it use "PCM" instead

获取音量

def get_volume(self):
    if self.platform == 'Linux':
        volume = subprocess.check_output('amixer get Master | grep Mono: | cut -d " " -f 6', 

shell=True)
volume = volume[1:-3]
elif self.platform == 'Darwin':
volume = subprocess.check_output('osascript -e "output volume of (get volume setti
ngs)"', shell=True)
else:
volume = ''
self.volume = volume

# 调整音量大小
def change_volume(self, increment):
    if increment == 1:
        volume = int(self.volume) + 5
    else:
        volume = int(self.volume) - 5
    if self.platform == 'Linux':
        subprocess.Popen('amixer set Master ' + str(volume) + '% >/dev/null 2>&1', shell=True

)

the way to fix it is just to replace the two words of "Master" in the code with "PCM"

in my system , i got the path of the douban.py
/usr/local/lib/python2.7/dist-packages/douban/douban.py

use an text editor to modify it, and restart your douban.fm, that's all.

after the fix , i got following, noted that i have "vol: 90% →" now

 Douban Fm \ retjiang   >>  64kbps  01:38  rate: ★ ★ ★ ★ ★   vol: 90%  →
