Request for Withdrawal


Dear Mr. Heyliger:


Pursuant to Rule 477(a) and (c) of the Securities Act of 1933, as amended (the “Securities Act”), PortalPlayer, Inc. (the “Registrant”) hereby requests the immediate withdrawal of its Registration Statement on Form S-1 (File No. 333-129209), together with all exhibits thereto (the “Registration Statement”), filed by the Registrant with the Securities and Exchange Commission (the “Commission”) on October 24, 2005. The Registrant is seeking withdrawal of the Registration Statement because of unfavorable market conditions. The Registrant requests that the Commission consent to this application on the grounds that the withdrawal of the Registration Statement is consistent with the public interest and the protection of investors, as contemplated by Rule 477(a) of the Securities Act.


The Registration Statement has not been declared effective. No securities under the Registration Statement have been sold. Although no decision has been made at this time, the Registrant may consider or undertake other financing options, including for example a private offering in reliance on Rule 155(c) under the Securities Act.
