Hi,
it seems there is a bug in card parsing (snd_card_get_index).
If the device name is "hw:0,1", then in _snd_dev_get_device, snd_card_get_index will be called with "0,1".
But snd_card_get_index expect to be called with only the card string number or name : it first check that the string is a number [1], and then try for each card to compare with the card name [2]
Indeed.
I don't know what suppose to do snd_card_get_index, but I thing a easy way to fix it is to pass to snd_card_get_index only the string before the first comma.
I think the patch below is much simpler. Could you check whether this works?
thanks,
Takashi
