Subject: CDC_PLAY_AUDIO check in cdrom_count_tracks() and other oddities
Date: Thu, 12 Jun 2008 12:51:28 +0900	[thread overview]
Message-ID: <48509D40.2060901@gmail.com> (raw)

Hello, Jens.

I'm tracking down a bug where HAL doesn't mount media automatically.
It turned out that CDROM_DISC_STATUS wasn't reporting correct disc
type which was caused by CDC_PLAY_AUDIO check failure at the top of
cdrom_count_tracks().

I've went through MMC-3 but couldn't find anything which associates
play audio capability with READ_TOC.  READ_TOC was mandatory command,
so according to MMC-3, there's no reason to avoid issuing READ_TOC on
!CDC_PLAY_AUDIO.  Is there something I don't know?

Thanks.
