Hi, On my laptop, which is not very old, they have dropped support for playing CD's through "cdcontrol". To play CD's one has to read the samples off the CD-ROM and send it to the soundcard in software. The problem is that the ATAPI driver complains when trying to read audio data:
acd0: WARNING - READ_CD UDMA ICRC error (retrying request) So I tried: sysctl hw.ata.atapi_dma=0 Which says I should put "hw.ata.atapi_dma=0" into a non-existent file. Then I tried: echo hw.ata.atapi_dma="0" >> /boot/device.hints And rebooted. Now things work. Why is PIO mode not selected automatically by the ATAPI driver? Hence obviously some manufacturers try to save money here, not supporting all modes for all mediums? UDMA works for data CD-ROM's though. --HPS _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
