[oss-devel] [PATCH] fix ossxmix breaking after USB disconnect

[Yair K.]

Hi,

   A Ubuntu thread[1] found a very likely issue in ossxmix - when a USB device is attached and detached OSS leaves an empty device object. ossxmix won't load (unless -d<dev#> is used) since SNDCTL_MIX_NREXT returns -1 and "SNDCTL_MIX_NREXT: No such device or address" . This *untested* (I don't have the hardware) patch checks SNDCTL_MIXER_INFO=>enabled to fix this bug (Also, some manpage cleanups).

Yours,
